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. WebFeb 1, 1990 · Leaching of nondolomitized grains in the mixed phreatic and meteoric-phreatic environments created large moldic pores. Diagenetic patterns follow structural and depositional trends so that suites of characteristic pore types exist for each facies.

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.
