Abstract

Abstract

In the Paleoproterozoic Lieryu Formation and Dashiqiao Formation, eastern Liaoning Province, China, are distributed the magnesium rich carbonate rock formations, where occur large to super large sized deposits of borax, magnesite, talc, and serpentine. The formation of these magnesian non metallic deposits related to the evaporites of the Paleoproterozoic experienced the regional metamorphism and the hydrothermal metasomatism during the Lüliang orogeny, and also the mineralization process of tectono magmatism during the Indosinian Yanshanian. In particular, the magnesian carbonate rock formations, minerogenetic structures and ore forming fluids played a key role in the formation of the magnesian non metallic deposits. Therefore, it can be concluded that these mineral deposits are end products of the integration of the coupling of the Paleoproterozoic ore source field, fluid field, thermal field (energy field) and stress field on certain time space conditions with the superimposed reformation of tectono magmatism in the later stage.
