The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.

组成这些钾质碱性岩带的岩石：在岩相上，包括深成相、浅成相和喷溢相等不同岩相；在岩性上，从超基性、基性、中性到酸性岩石；造岩矿物，从超基性到酸性岩石中均有透辉石，在基性、超基性岩中有霞石；在岩石化学成分上，所有岩石均表现出富碱高钾富钙，微量元素富集Rb、Sr、Ba等大离子亲石元素和Th、U等放射性元素，贫Nb、Ta、Zr、Hf等高场强元素；稀土元素富集轻稀土，铕负异常不明显；Sr、Nd、Pb同位素组成，显示了物质来源于富集地幔源区。

By the introduction of geotectonics,mineralized geological background and characters of several epithermal gold deposits in Southeast Asia,the ore-forming circumstance and its causes of changes,mineralizing materials' sources and the main reasons for gold deposition in different conditions was discussed.

文章介绍了东南亚地区几个浅成低温热液金矿床的成矿地质背景、矿床地质特征，分析了矿床形成环境及变化的原因、成矿物质来源和导致金在不同环境下沉淀的主要因素，并讨论了浅成低温热液矿床形成的几个问题。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。

通过对二道沟金矿床矿物学的详细研究和对比，表明该矿床低温热液矿物组合和低温热液蚀变十分发育；与典型的冰长石-绢云母型浅成热液金矿的矿物组合十分相似；其应属于与流纹熔岩及其火山碎屑岩密切相关的浅成热液型金矿床

If the bath is blue, wall tiles can be equipped with light blue, dark blue ground angel; If the bath is jujube red, pink walls with tiles, the ground angel red; If the bath is white, the walls are chosen white background shallow periods spent tiles, and pink tiles on the ground supported.

如果浴缸是蓝色的，则墙壁瓷砖就可以配浅蓝色的，地面配成深蓝色的；如浴缸是枣红色的，则墙壁贴粉红色瓷砖，地面配成红色的；如浴缸是白色的，墙壁则选用白底浅粉色花的瓷砖，而地面配以粉红色地砖。
