Paleokarsts at Unconformities: ABSTRACT
AAPG Bulletin, 1982The awareness of the importance of subaerial exposure in the diagenesis of limestones has led to the recognition of a variety of subaerial phenomena in carbonate sequences such as vadose cements and calcrete crusts. Other such phenomena include paleokarsts, of which there are surprisingly few detailed descriptions. One problem in recognizing paleokarst

Fluid prediction for paleokarst carbonate reservoir
SEG Technical Program Expanded Abstracts 2015, 2015Summary Ordovician paleokarst carbonate reservoirs are widely developed in the Tahe Oilfield, China. The storage space is complex, mainly including dissolved caves, pores and fractures, which significantly influence the seismic velocity. In order to accurately discriminate the saturated pore fluids, DEM-Gassmann rock physic model is employed to address

Karst is a term used to describe the processes and products of the natural dissolution of soluble rocks, usually limestone. It produces a distinctive suite of surface geomorphological features on scales of millimeter to kilometer. Many karst landforms are intimately linked to underground drainage systems, or caves, which are an integral component of ...

Ordovician Knox Paleokarst Unconformity, Appalachians
1988The Ordovician Knox unconformity in the Appalachians developed in less than 10 m.y. during a time of initial collision of the passive margin and of eu- static sealevel lowering. It formed on cyclic limestones and dolomites of the 200- to 1200-m-thick Upper Knox-Beekmantown Group, and provides an example of the effects of long-term exposure on a ...

Paleokarst Related Hydrocarbon Reservoirs
1993Abstract This volume is a compilation of papers relative to paleokarst and associated reservoirs. The examples illustrate many of the rock types, and stratigraphic, structural, and paleotopographic features of carbonate strata which result chiefly from solution and collapse due to ingress of meteoric waters at and below unconformities ...

Karst-type ore deposits are a major new discovery in many countries made by many mining geologists during the past decade. The present paper offers a case study of an area in southern Sardinia where karstification took place at various intervals, producing superimposed karst systems and local sulphide-barite concentrations.

Paleokarst-Controlled Ore in Central Colorado
1988Abstract We propose that many Tertiary man to orebodies typical of Leadville and adjacent districts of Central Colorado (northern Sawatch range and Mosquito range) are modifications to pre-existing mineralized paleokarst cave systems (Tschauder and Landis, 1985; Landis and Tschauder, 1985).

Paleokarst as a target for modern karstification
Carbonates and Evaporites, 1995Paleokarst phenomena are those that at present or for some duration in the past have been decoupled from all active hydrogeochemical systems. They are widely distributed geographically and are recognized from the Lower Proterozoic onwards in the geological record. Amongst the many fascinating features that they offer for study is their exploitation as “
