Abstract
Calcite veins in Mesozoic sedimentary rock localities are found in the southern part of Lam Sonthi district, Lopburi province, in central Thailand, near the Loei-Petchabun fold belt regions. The vein’s host rocks are siliciclastic rocks, primarily mudstone and sandstone. The main aim of this study is to learn more about calcite vein geometry and development, as well as the structural evolution of calcite veins in the Phu Kradung formation in the Lam Sonthi area of Lopburi province. A petrographic and structural analysis of the veins was performed to examine the kinematics and geological structures of the calcite vein in the host rock. The findings show three basic variants of the orientation of calcite veins, including east-dipping calcite veins, west-dipping calcite veins, and steep-dip-angle calcite veins. The majority of the calcite veins in the study area show common characteristics of fibrous crystals. So, most of them are considered the antitaxial veins. The formation of the calcite vein is divided into four stages, including the formation stage of the host rock Phu Kradung Formation, the deformation stage, which causes the formation to show a gentle fold with the east-dipping veins and the west-dipping veins generated by the E-W compression. As a result, the host rock develops multiple thrust faults, resulting in the formation of fault-related veins. The final stage is the opening of the steep-dip-angle vein over each geologic stratum in the study area.
