Inner Temple before Taipusiqi to rock geochemical characteristics and metallogenic prognosis

Title: Inner Temple before Taipusiqi to rock geochemical characteristics and metallogenic prognosis Author: Wu Cuihua Degree-granting units: Central South University Keywords: granite;; geochemistry;; metallogenic prognosis;; northern margin of the North China block;; Taipusiqi Summary:

Mine is located in the former temple in the northern margin of the North China block, is Proterozoic rift zone of copper and zinc cobalt-platinum-gold metallogenic belt in eastern Zhengxiangbaiqi - Toronto gold metal into a lead-zinc mine, its great potential for more and more ore valued by the majority of scholars. However, relatively little investment in geological work of its Neodymium Magnets exploration work in this area has not been a major breakthrough.

By detailed field geological survey, to collect a lot of geological information, collected a large number of rock and mineral samples and specimens, the use of petrology, structural geology, mineralogy, ore deposits, geochemistry, mineralization predictions, exploration and other multi-disciplinary knowledge , from the northern margin of North China block is to start regional geological features, in-depth study of the temple in the region before the formation, structure, and mineralization of magmatic rocks and their relationship, focusing on analysis of the granite features of this area. Summed up the area before the temple in prospecting potential, and predicted the exploration target.

Prior to analysis by comparing the temple to rock rock rock and Shagou characteristics and geochemical characteristics of granitoids in this area that the high silica (> 56%), calc-alkaline (σ is 0.98-1.57), quasi-aluminum (A / CNK close to 1.1) and granodiorite - tonalite granitoid rocks and K-feldspar, Na-rich lithology (Na2O than K2O) type Ⅰ intrusive rocks. The former is part of the temple to rock with like "S" type characteristics of granite, and more http://www.everbeenmagnet.com/en/products/110-sintered-neodymium-magnets alkaline, with a low index of differentiation characteristics ((DI <88)). Mg # index (0.20-0.33) and δEu (former temple to rock a weak negative anomaly to positive anomaly) indicate an initial magma derived from partial melting of lower crustal rocks directly, for the magnetite series granite, with a low total REE (40.39 × 10-6-46.91 × 10-6) and the severity of the REE fractionation is not obvious (ω (LaN) / ω (YbN) of 1.68-6.35) characteristics. This is the first to rock that is made before the temple of gold mineralization in this area rock, and the intrusion of the former temple to rock for the gold is providing a power source, that the mineralization in this area has excellent conditions.

In the background of the area's geological, geological conditions, alteration and mineralization of ore controlling factors on the basis of comprehensive analysis of the information presented four exploration target. Degree Year: 2010
