     · shows broken shell fragments at places. Marls are generally compacted and cleaved and also show some hard substrate at places. Marly limestone is generally light grey to medium grey and thin bedded to medium bedded with occasional thick beds. It is generally unfossiliferous and contains some burrows which are

Oologah limestone immediately above shale interval contain irregularlyshaped chert pods most of which have been weathered out along with fossil components suggesting paleokarst erosion may have occurred. Unit thins considerably to the south and west and most likely pinching out just north of the Arkansas River beneath the terrace cover.

    Sedimentary rockSedimentary rock Limestones and dolomites Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg CO3 2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones although the exact details of this dolomitization process

    Weathering ErosionIntroduction to Geomorphological

     · Erosion. Erosion is the removal (transport) of weathered rock materials downslope and away from their original site of weathering. Erosion processes are driven primarily by the force of gravity which may be aided by a flowing medium such as water ( rivers) and ice ( glaciers) or

    Weathering Influence on Properties of Siltstones from

    201667 · Slaking and weathering of weak rocks result in slope instability. Siltstones from flysch rock masses are highly susceptible to weathering which causes rapid changes in the geotechnical properties and durability. This study investigated siltstone samples of different weathering grades from flysch rock masses from the Istria Peninsula Croatia and determined the effects of weathering on their
