Multiple-aged granitoids and related tungsten-tin mineralization in the Nanling Range, South china

The Nanling metallogenic belt in South china is characterized by well-developed tungsten-tin mineralization related to multi- ple-aged granitoids. This belt is one of the 5 key prospecting and exploration areas among the 1. impor{1.t metallogenic tar- gets in china. Impor{1.t progress has been made in recent years in unders{1.ding the Nanling granitoids and associated miner- alization, and this paper introduces the latest major findings as follows：（1. there exists a series of Caledonian, Indosinian, and Yanshanian W-Sn-bearing granites; （2） the Sn-bearing Yanshanian granites in the Nanling Range form an NE-SW trending aluminous A-type granite belt that stretches over 350 km. The granites typically belong to the magnetite series, and dioritic micro-granular enclaves with mingling features are very common; （3） the Early Yanshanian Sn- and W-bearing granites pos- sess different petrological and geochemical features to each other： most Sn-bearing granites are metaluminous to weakly per- aluminous biotite （hornblende） granites, with zircon tHe（t） values of ca. -2 to -8, whereas most W-bearing granites are peralu- minous two-mica granites or muscovite granites with CHf（t） values of ca. -8 to -1.; （4） based on the petrology and geochemis- try of the W-Sn-bearing granites, mineralogical studies have shown that common minerals such as ti{1.ite, magnetite, and bio- tite may be used as indicators for discriminating the mineralizing potential of the Sn-bearing granites. Similarly, W-bearing minerals such as wolframite may indicate the mineralizing potential of the W-bearing granites. Future studies should be fo- cused on examining the internal relationships between the multiple-aged granites in composite bodies, the metallogenic pecu- liarities of multiple-aged W-Sn-bearing granites, the links between melt evolution and highly evolved ore-bearing felsic dykes, and the connections between granite domes and mineralization.

为了探究低分子有机酸(柠檬酸和苹果酸)对Cr污染土壤中Cr形态分布的影响,以淮南市潘一矿煤矸石山周边的复垦土壤为研究对象,通过模拟不同浓度Cr污染土壤,分析柠檬酸(CA)和苹果酸(ma)对土壤中Cr赋存形态的影响机制。结果表明:(1.随着外源Cr浓度的增加,土壤中Cr的活性有效提高。(2)柠檬酸和苹果酸的加入均可增加土壤中可交换态Cr的占比,即Cr的有效性得到提高,且随着柠檬酸和苹果酸浓度的升高,对土壤中Cr活化效果持续上升,柠檬酸的活化效果优于苹果酸。(3)随着老化时间的延长,有机酸对Cr的活化效果会减弱,弱结合态Cr将逐渐向强结合态Cr转化。因此,土壤重金属Cr污染修复中,可以考虑选用活化效果较好的柠檬酸作为修复辅助剂,来提升土壤Cr修复效率。研究结果可为矿区复垦土壤重金属Cr污染修复提供指导。
