Liaoning Province Jade Resources Research And Evaluation

Ancient dark clouds two long granite and liaohe group of rich magnesium carbonate rockcontact zone mineralization favorable for location,the ancient world of liaohe group ofDaShiQiao high calcium magnesium carbonate rock (dolomite marble) for the primitive beds,ancient dark clouds two long granite for forming the granite provide heat source,in the late veinrocks for the formation of the jade role, its layers of pressure and fault to ore control and storemineral structure. The jade of high pressure and temperature in SiO2of unsaturated closing ingeological environment, jade in the ore-forming temperature of223~392°C.Hydrogen andoxygen isotopic analysis showed the jade hydrothermal ore-forming water from the mainregional metamorphism water,part for mixed magma water; Sulfur isotope analysis shows thatthe sulfur source for sedimentary origin; Jade and marble rare earth mode contrast, both havesimilar features, show that the jade of rare earth elements from surrounding rock marble. Controlof layer crack control of temperature type-type hydrothermal ore deposit account. This articlethrough the jade the mineralization of regional geological background, the genesis, metallogenicmodel, geological characteristics and regional metallogenic studies, sure liaohe group ofDaShiQiao group three sections of the serpentine dolomitic marble is the wild major prospectingmarks, and metallogenic prospective area of screening and evaluation the key vision zone, thispaper aims to provide the reference for finding more rich jade resources.
