WebBone histology has proved to be a valuable tool to obtain information about the palaeobiology and early taphonomic history of fossil vertebrates. However, there are still many extinct taxa for which bone histology studies could be applied to deduce information about their life history and early diagenetic changes. WebDiagenetic History of the Sussex "B" Sandstone.

WebJan 1, 1991 · The most extensive diagenetic alteration of both Trenton and Black River limestones has occurred in fracture-controlled hydrocarbon reservoirs. Within reservoirs several stages of dolomitization were followed by carbonate and sulfate cementation, and sulfide mineralization. WebThe formation has undergone for the most part a single burial/exhumation cycle which facilitates reconstruction of the diagenetic history (McCrory and others, 1995). 2.) The formation undergoes a complex diagenetic evolution during burial which potentially can be correlated with stages of vein cementation. This sequence is apparently due to the ...
WebVolumetrically, silica and carbonate cementation were the most important diagenetic processes. Chlorite is the dominant authigenic clay mineral. Porosity is predominantly secondary, and the dissolution of quartz and quartz overgrowths provided much of the reservoir in these highly productive strata.
