Stylolite networks and their insoluble residues (IR) are among the major concerns and the fundamental controls on the mining and processing of sedimentary decorative stones, largely made from dolomitized limestones. They are mainly used, as natural rock blocks and polished slabs, to construct and decorate floors and walls of buildings and monuments. Representative quarries in Khur areas, east o...

The Ediacaran Dengying Formation in Central Sichuan Basin is the deep dolomite gas reservoir with largest natural reserves China, providing an excellent example for understanding effect of diagenesis evolution on quality. By integrating petrology, geochemistry and situ U-Pb dating, this study aims to reveal genesis different rock fabrics their corresponding diagenetic events, discuss temporal r...

Through optical microscopic examination, scanning electron microscope analysis, whole rock X-ray diffraction fluorescence spectrum carbon and oxygen isotope temperature measurement of fluid inclusions, the characteristics formation mechanism alkaline lacustrine tight oil reservoirs Permian Fengcheng Formation in Mahu Sag Junggar Basin have been systematically studied, a genetic model has propos...

Fluid systems in inverted rifted margins are challenging to interpret because fractures formed before compression were often reactivated acting as fluid pathways new ones formed. Deciphering the fracture and flow history such complex settings has key implications for prediction of distribution mineral resources. As an example, we reconstruct evolution a portion Pyrenean rift, Upper Pedraforca t...
