The application of structured‐light illumination microscopy to hydrocarbon‐bearing fluid inclusions

Structured‐light illumination (SLI)‐based microscopy offers geologists a new perspective for screening of hydrocarbon‐bearing (HCFI) and small aqueous fluid inclusion (AFI) assemblages. This optical‐sectioning technique provides rapid, confocal‐like imaging, using relatively simple and inexpensive instrumentation. The 3D fluorescent images of HCFI planes and large single HCFIs permit the visualization of the relationships between HCFI assemblages, examination of HCFI morphology, and volume estimates of the fluorescent components within HCFIs. By the use of normal white light illumination, SLI image capture, and varying acquisition time it is also possible to image AFI because of the random movements of vapour bubbles within the inclusions. This allows the near‐simultaneous visualization of hydrocarbon and AFI which is of significant importance for the study of sedimentary basins and petroleum reservoirs. SLI is a unique and accessible 3D petrographic tool, with practical advantages over conventional epifluorescence and confocal laser scanning microscopy.     

3. THE NOSTALGIAS FOR EMPIRE

The aim of this article is to explore the theoretical and practical differences between colonial and imperial nostalgia. It opens with a substantial theoretical discussion of the relevant scholarship followed by an analysis of the nostalgias of empire. Nostalgia, in relation to empire, is usually analyzed as a longing for a period of former imperial and colonial glory, thus blurring the various hegemonic practices associated with empire. This elision arises out of the fact colonialism was integral to European imperialism. Yet there is a significant distinction between imperial and colonial nostalgia. With its main focus on postcolonial society in France and Britain, the article will theorize the differences between them, arguing that one is connected to the loss of global power and the other to the loss of a socioeconomic lifestyle. It will explore the way in which these two types of nostalgia are constructed and historicized, examining their differences from historical memory through the responses of both former colonizing and colonized individuals or groups. It will demonstrate that collective nostalgia is not merely a “feel‐good” sentiment about an idealized political or socioeconomic past, but can be readily connected to coming to terms with past trauma(s) thus being a mechanism to elide violence experienced and violence perpetrated by highlighting one to the detriment of the other.
