The image below shows metamorphism related to the emplacement of an igneous pluton. Weathering. Deposition mainly takes place at the mouth of a stream or a river through a process known as horizontal sorting (Carnicelli). In the past large quantities of soapstone were excavated from outcrops south of Llano, Texas, and ground for use as insecticide carrier and inert filler in various products. The reworked conodonts and the Burnam Limestone indicate that the region of the Llano Uplift was likely either partially and briefly submerged during the Middle and Upper Ordovician only to have the sediments deposited during these inundations removed by later erosion.
