“清江四案”“白银案”之前后

锦屏本地苗族木商向政府状告外省木商使用冲铅银两假币的诉讼案件。收集到的两件状词,一是道光七年（1827）由李荣魁带头起诉到贵州布政使司批转黎平府的公文,又由黎平府作出处理公告;另件是光绪十三年（1887）姜名卿等向黎平府递交的状纸。两起案件相隔60年,因为假银泛滥、受害深重后才产生诉讼,政府行文禁止后,仍禁而不止,所以少数民族的木商、林农和从事木材运输的农民工,受假银之害至少在80年以上。但从外省木商之滥用假币,折射出清水江木业之兴旺。

High‐temperature magmatic fluid exsolved from magma at the Duobuza porphyry copper–gold deposit,Northern Tibet

The Duobuza porphyry copper–gold deposit (proven Cu resources of 2.7 Mt, 0.94% Cu and 13 t gold, 0.21 g t^?1 Au) is located at the northern margin of the Bangong‐Nujiang suture zone separating the Qiangtang and Lhasa Terranes. The major ore‐bearing porphyry consists of granodiorite. The alteration zone extends from silicification and potassic alteration close to the porphyry stock to moderate argillic alteration and propylitization further out. Phyllic alteration is not well developed. Sericite‐quartz veins only occur locally. High‐temperature, high‐salinity fluid inclusions were observed in quartz phenocrysts and various quartz veins. These fluid inclusions are characterized by sylvite dissolution between 180 and 360°C and halite dissolution between 240 and 540°C, followed by homogenization through vapor disappearance between 620 and 960°C. Daughter minerals were identified by SEM as chalcopyrite, halite, sylvite, rutile, K–feldspar, and Fe–Mn‐chloride. They indicate that the fluid is rich in ore‐forming elements and of high oxidation state. The fluid belongs to a complex hydrothermal system containing H₂O – NaCl – KCl ± FeCl₂ ± CaCl₂ ± MnCl₂. With decreasing homogenization temperature, the fluid salinity tends to increase from 34 to 82 wt% NaCl equiv., possibly suggesting a pressure or Cl/H₂O increase in the original magma. No coexisting vapor‐rich fluid inclusions with similar homogenization temperatures were found, so the brines are interpreted to have formed by direct exsolution from magma rather than trough boiling off of a low‐salinity vapor. Estimated minimum pressure of 160 MPa imply approximately 7‐km depth. This indicates that the deposit represents an orthomagmatic end member of the porphyry copper deposit continuum. Two key factors are proposed for the fluid evolution responsible for the large size of the gold‐rich porphyry copper deposit of Duobuza: (i) ore‐forming fluids separated early from the magma, and (ii) the hydrothermal fluid system was of magmatic origin and highly oxidized.     

Humayma's notched peak: a focus of Nabataean and Roman veneration and civic identity

The most distinctive landscape feature at the southern Jordanian site of Humayma is Jebel Qalkha's highest peak, which is split at the top by a wide notch. The Nabataean town of Hawara (Roman Hauarra/Hauara) was built on the plain immediately east of this peak. This paper draws on the site's foundation myth, petroglyphs, betyls and religious and civic structures to illustrate the significance of this notched peak for the site's ancient populations. The evidence suggests that this distinctive peak served as a focus of veneration and a marker of civic identity for Humayma's Nabataean and Roman inhabitants.     

Geographic film as public research: re-visualizing/vitalizing a terraced landscape in the Italian Alps (Piccola terra/Small land, 2012)

This article describes an experience of geographic filmmaking carried out within a long-term research process (2000–2012) involving the terraced landscape of the Brenta Valley in the Italian Alps. The documentary Piccola terra [Small land] (2012) was co-produced by geographers and professional directors. Engaging in the recent debate on filmic geographies, the aim of this article is to discuss and show what makes a film ‘geographic’. The geographer authored a filmic interpretation of landscape which is spatially and temporally complex, open and mobile, anchored to material features and to personal stories and socio-economic contexts. Produced to support a campaign for the adoption of abandoned terraces by ‘new farmers’, the documentary Piccola terra serves as a means to engage society and produce landscape change. Geographic filmmaking as an action-, public- and social-oriented activity is discussed with reference to the so-called ‘impact agenda’. We propose a style of active engagement through filmmaking which is workable, rather than critical. In order to avoid purely auto-reflective, auto-referential academic speculation on doing filmic and public geographies, this paper, which ideally is read along with viewing of the documentary, materially enters the researched/filmed landscape, developing into a supplementary tool for the international dissemination of Piccola terra.     

The Early Settlement of South Norway after the Last Deglaciation: A Diasporic Perspective

Based on a theoretical approach of diaspora theory and the use of ethnographical comparative analysis, it is argued that the early settlement of South Norway probably brought about diasporic conditions. Archaeological and natural science records are applied to discuss the migrations of mobile hunter-gatherers with a shamanistic reindeer culture from the Continent, after deglaciation of the Weichselian ice cap. This paper discusses the diasporic people's identity, their survival as a group, their adaptation to the new environment and the development of an independent reindeer culture characterized by relics and meeting places, after the break in the regular contact between people in the area of origin and South Norway.     

Spectrographic Analyses of Mycenaean Pottery from Ialysos on Rhodes: Results and Implications

Abstract

The changing relations between the important Mycenaean site of Ialysos on Rhodes and the Argolid (in the Greek Peloponnese) during the LH III period (the 15th-12th centuries B.C.) have been studied through the pottery found in the tombs of the cemetery from Ialysos. The results of spectrographic analyses of well characterised and dated pots from Ialysos have made possible a clear distinction between locally produced Rhodian pottery and imports that were primarily from the Argolid. During the LH IIIA2 period the large majority of the cemetery pottery at Ialysos was imported from the Argolid. The same situation pertains in the IIIB period, but there are examples of imported pottery from centres other than the Argolid, such as Crete. In the 12th century B.C. (IIIC), however, the position was completely reversed, and the fine Mycenaean pottery was almost exclusively made on Rhodes.     

Feeding the Mountains: Sacred Landscapes,Mountain Worship,and Sacrifice in the Maya and Inca Worlds

Three texts reviewed here address the linkages between religion and mountainous landscapes in the Maya and Inca realms. Bassie-Sweet provides a thorough analysis of the Maya mythologies of creation and situates its players and concepts within the real world. Besom thoughtfully tackles the place of mountains and child sacrifice within the Andes with a focus on the late prehispanic Inca. Reinhard and Constanza offer a detailed and richly illustrated case study of state-sponsored child sacrifice on a mountaintop in the south of the Inca Empire. Taken together, these somewhat disparate books produce several fascinating parallels in the sacred geographies of mountains and the offerings made to them.     

Perceptual images of Conimbriga using High Dynamic Range

It is widely recognized that new technologies can play an important role in the interpretation of our cultural heritage legacy. This has become a powerful tool providing a better understanding of our past, and thereby, allowing us to attain a glimpse of the environments in which our ancestors lived. In this domain, the way we see such reconstructed environments is particularly important in order to establish an accurate interpretation of that historical setting. However, the desired visual accuracy in the representation of any archaeological scenario is strictly related to the technology used to visualize it. High Dynamic Range (HDR) technology encompasses the capacity to produce visual results similar to the visual acuity of the human eye, particularly in extreme lighting conditions, such as bright light or dim environments.     

Geospatial modeling of pedestrian transportation networks: a case study from precolumbian Oaxaca,Mexico

Using accumulated cost surfaces and various pathfinding techniques within Geographic Information Systems (GIS) software, archaeologists and other spatial scientists have developed increasingly sophisticated models of human movement. Despite their utility, these approaches can be limited because standard GIS software cannot model movement (1) from many origins to many destinations or (2) without specific origins and destinations. Absent these capabilities, it is particularly difficult to model networks of movement over a given tract of land if you are interested in obtaining a more general sense of movement dynamics, not specific site-to-site patterns. In this paper, we present an innovative way of modeling past movement that generates both natural-looking networks and also indicates the degree of traffic that may have existed on any particular segment of those networks. The “From Everywhere to Everywhere” (FETE) model generates networks based on topography and landcover without requiring that origin and destination points be supplied in advance. We apply the FETE model to a case from the southern Mexican state of Oaxaca, a region that has extensive archaeological and ethnohistoric data sets that serve as a test of the efficacy of our technique. A comparison of the FETE output with known late precolumbian and early colonial movement corridors indicates that the method is effective and should be useful for modeling networks in other areas.
