Abstract

The use of phosphate analysis in archaeology is possible because past human occupation and activities increased the amount of soil phosphorus in the areas occupied. The accumulated phosphorus in archaeological deposits tends to remain constant through time and is measurable through soil sampling and chemical analysis, thereby providing archaeology with a valuable tool, applicable to a wide variety of research situations. Phosphate analysis is especially useful in surveying large areas to locate and delimit sites.  相似文献

Gauged river runoff records extend only over limited timespans, mostly commencing post‐1940. Historical sources can provide additional material to assist in extending the hydrological record into the nineteenth century and earlier. Such sources vary, however, in the nature of the detail, in their reliability and in their potential use in hydrological reconstruction. This paper outlines the main categories of sources available, subdivided into those which have been authenticated and those of variable reliability.  相似文献

Abstract

My personal recollection of the ‘relevance revolution’ in the 1970s is that it was a reaction to a quantitative geography that was overly-focused on technique and under-concerned with real-world issues. The consequent search for relevance took the form of a commitment to liberal- and left-leaning ideologies and issues. This differed from concepts of relevance as pertinence/timeliness, or as applied geography. Postmodern thought is significant in current debates on relevance in all three of its manifestations: relevance as commitment, pertinence and application.  相似文献
