The electron and hole centers in qttartz are of great significance in goldprospecting. The existence of such centers. is attributed to defects in crystalsresulting from isomorphism between cations of different valences. The common hole centers in quartz include Al--O~-, Ti--O~- and Fe-O~-, while electron centerscomprise Al~(3+) + M, Fe~(3+) + M, Ti~(3+) + M etc. Electron paramagnetic tesonance andthermoluminescence are effective methods for detecting electron and hole cen-ters.

The electron and hole centers in qttartz are of great significance in goldprospecting. The existence of such centers. is attributed to defects in crystalsresulting from isomorphism between cations of different valences. The common hole centers in quartz include Al--O~-, Ti--O~- and Fe-O~-, while electron centerscomprise Al~(3+) + M, Fe~(3+) + M, Ti~(3+) + M etc. Electron paramagnetic tesonance andthermoluminescence are effective methods for detecting electron and hole cen-ters. In quartz from gold deposits, the Al--O~- hole center shows positive cortela-tion with gold concentration. The number and intensity of peaks of the ther-moluminescent cutves are obviously related to stages of gold mineralization:the curve of the early barren quartz shows nearly Symmetric pattern; that ofthe major stage auriferous quartz is of multimodal type; the curve of the latequartz, low in gold, is marked by unimodal--bimodal type with rather intenseluminescence. The thermoluminescence of quartz is connected to certain extent with dis--tribution of orebodies: the bimodal or multimodal curve commonly indicatesorebodies, whereas the unimodal curve usually marks country rocks. Vertically,the intensity of thermoluminescence tends to increase with the buried depthof the orebody. The thermoluminescence curve of auriferous quartz is usually of multimo--dal type, with. the principal peaks generally negatively skewed. The barrenquartz usually has an asymmetric, gentle and unimodal type curve with weakintensity of luminescence.)

石英的电子-空穴心在金矿找矿勘探中具有重要意义。阳离子不等价类质同象造成的晶体缺陷,是使其具有电子-空穴心的内在因素。石英中常见的空穴心有Al-O~-、Ti-O~-、Fe-O~-,电子心有Al~(3+)+M、Fe~(3+)+M、Ti~(3+)+M等。电子顺磁共振波谱和热发光是检测石英中电子-空穴心的有效方法。在金矿床中,石英Al-O~-顺磁空穴心浓度较大者,其含金量也比较高。石英热发光曲线的发光峰的数量和强度与金成矿阶段有着明显的关系:早期成矿阶段结晶的基本不含金石英,热发光曲线常为近对称的单峰型,发光强度较大;主成矿阶段形成的含金石英,热发光曲线为多峰型,常具最大的发光强度;晚期成矿阶段生成的含金性较差的右英,热发光曲线呈单峰-双峰型,发光强度亦较大。石英热发光性与金矿体的空间展布表现出一定的联系;在矿体横向上,矿体中石英热发光曲线多为双峰-多峰型,围岩中石英热发光曲线多呈单峰型;在矿体垂向上,随矿体埋深的增加,石英热发光强度有逐渐增大的趋势。含金石英通常具有多个热发光温度,曲线形态为多峰型,且主热发光峰多位于相对较低的温度区间;不含金石英常仅有一个热发光温度,曲线形态为不对称的较平缓的单峰型,或为一平缓的...

Most fluorite deposits from Guangdong, Fujian and Jiangxi Provinces of South China occur in the endo-or exdo-contact zone of granite intrusions. The major mechanism of mineralization is vein filling (metasomatism), strictly controlled by NEstriking structures. The REE content in fluorite ranges from 100 × 10_(-6) to 200 ×10_(-6), and increases with increasing REE content of the country rock and the increasing green degree of fluorite, but decreases with the increasing intensity of alteration of the country rock...

Most fluorite deposits from Guangdong, Fujian and Jiangxi Provinces of South China occur in the endo-or exdo-contact zone of granite intrusions. The major mechanism of mineralization is vein filling (metasomatism), strictly controlled by NEstriking structures. The REE content in fluorite ranges from 100 × 10_(-6) to 200 ×10_(-6), and increases with increasing REE content of the country rock and the increasing green degree of fluorite, but decreases with the increasing intensity of alteration of the country rock and mineralization from early to late. The REE distribution pattern of fluorite inclines toward the right, which is similar to those of the biotite granite and the biotite from the granite. Fluorite is projected into near the MREE or HREE end, and the country rock near the LREE end on the REE ternary diagram. On the Moller's 'Tb/Ca-Tb/La diagram, fluorite from the granite falls into the hydrothermal field, whereas fluorite. from terrigenous carbonate rocks (in the contact zone of marine volcanic-sedimentary rocks and sedimentary carbonates)and sedimentary carbonates are projected below the field of fluorite of granite, even into the sedimentary field. Fluorite in the volcanic rocks are above the granite field. Apparently, this kind of epithermal deposit is only related to the lithology of the country rocks on the Moller's diagram. It is concluded that the epithermal vein-type fluorite deposits in South China formed after granitism. The ore-forming solution is the heated meteoric water, which constantly leached F, Ca and REE out of the country rock. By this way, the ore elements are reactivated, transported, and finally deposited in favorable sites.

华南地区广东、福建、江西等省内的萤石矿床,多数处于花岗岩的内外接触带上。成矿方式为脉状充填(交代)式。成矿严格受中国东部北东向构造控制。近百个样品稀土分析表明,萤石中稀土含量为100×10~(-6)-200×10~(-6),并且随着围岩中稀土含量的增加和萤石绿度的增加而增高,随着围岩蚀变强度的增强和矿化由早到晚而降低。萤石中的稀土配分曲线为右倾斜的平缓曲线,与黑云母花岗岩及其中的黑云母具有相似性和同步性。在稀土组成三角图中,由围岩到萤石,向中或重稀土转移。在Molleretal.的Tb/Ca-Tb/La图中,这类与花岗岩有关的萤石均落在热液区中间部位。产于陆源碳酸盐岩(海相火山沉积岩与沉积碳酸盐接触面)中的以及产于沉积碳酸盐中的萤石,处于花岗岩的下部,而与火山岩有关的处于花岗岩之上。显然在Molleretal.的图中,此类低温热液矿床的位置,仅与围岩的岩性有关。研究后确认,华南低温热液脉状萤石矿床,是在花岗宕及与其接触的其他岩石成岩后,由大气降水组成的地下热水溶液,不断对围岩进行淋滤,使Ca、F、REE等重新活化、转移,最后成矿的。
