| 1. | The contents of organic material, limonite and manganese hydroxides influence the variation of ore element . 有机物、褐铁矿和氧化锰的含量影响着成矿元素含量的变异。 |
| 2. | Tectonic geochemistry of gold - sliver metallogenetic elements 银等成矿元素的构造地球化学行为 |
| 3. | Characteristics of main ore - host strata and their metallogenic elements in wudang - yunxi and yun - xian region 两郧地区主要赋矿地层及其成矿元素 |
| 4. | The ores are all dominated by cu with minor zn , and the deposits are classified as the cu type 矿石主成矿元素均以铜为主,含少量的锌,几乎不含铅,矿床类型属于铜型。 |
| 5. | It has evident alpine - gorge incision and well - developed vegetation below slope , which are obviously unfavorable for granule mechanic motion 该地区不同粒级水系沉积物中成矿元素变化趋势一致,含量衰减迅速且在细粒级富集,并主要为硫化物相。 |
| 6. | This paper systemically contrasts and analyses the background value and its distribution , the relationship between element enrichment and ore - foming of the four units 依据1 : 20万水系沉积物测量数据,对比分析了主要成矿元素在整个成矿带及4个构造单元的背景值、元素的空间分布规律、元素富集特征及其与成矿的关系等。 |
| 7. | By the time of yanshanian structural hydrothermal superimposed caused the ore - forming chemical element of the pyritization sources activated , it results from the elements had been moving and expected turning into minerals in the beneficial structural position 经燕山期构造热液的叠加,驱使矿源层中的成矿元素活化、迁移,在有利的构造部位富集成矿。 |
| 8. | It belongs to nacl - h2o - co2 system . the ore - forming element assemblage is as - sb - cu - ni - u with high contents of as and sb . the stable isotope data show the metallogenic fluid comes from the mixture of magmatic water with meteoric water and stratum water 流体中成矿元素组合为as - sb - cu - ni - u ,总体上具较高的sb , as含量;稳定同位素特征表明成矿溶液主要来自岩浆水与大气降水、沉积盆地地层水的混合。 |
| 9. | Through studying the process of the dissolution and remobilization of ore - forming elements as well as the formation of various sorts of active phase state at surface , this paper probes into the mechanism of applying the organic phase state of elements to the exploration of concealed metallic deposits , illustrares the technique for extracting organic phase state of elements and gives case histories 摘要通过成矿元素的溶解、再迁移及在地表形成各种活动相态的过程,探讨利用元素有机相态勘查隐伏金属矿床的机理,并介绍元素有机相态的提取技术及矿例。 |
| 10. | Mineralization conditions are multiple , abnormity of geochemical exp1oration related with the symbiotic association of the elements in the main mineralization is also multiple . the association of different elements appears some optimum proportion under the mineralization conditions , known as ration composite anomaly 成矿条件是多元的,与主成矿元素共生组合具有某种对应关系的化探异常也是多元的,其元素组合在成矿条件下呈某种最佳比例关系,称为定量组合异常。 |
