Postdoctor LI Kaikai and professor CAI Chunfang clarify the origin of palaeo-waters in the Ordovician carbonates in Tahe oilfield, Tarim Basin: constraints from fluid inclusions and Sr, C and O isotopes.

They present fluid-inclusion data, trace element compositions, and strontium, carbon, and oxygen isotopes from the fracture-filling, karst-filling and interparticle calcite cements and formation water in the Ordovician in Tahe area.

Fluid-inclusion data can be used to indicate temperatures and salinities during mineralization, and Sr, C, and O isotopic compositions have widely been used to indicate the origin of waters, mixing of different water bodies, and cross-formation water flow.
