黑龙江省农业地球化学初步研究   总被引：4，自引：1，他引：4  

葛晓立  吴锡生 《物探与化探》1996,20(1):40-48

本文采用对比分析等数据处理方法将黑龙江省1:50万区域地球化学资料应用于农业问题的研究。通过将该省主要农作物产量与土壤、水系沉积物中地球化学元素分布进行对比,发现农作物产量与微量元素含量之间存在一定关联,其中Co对大豆,Zn对甜菜、小麦、水稻等农作物产量具有明显的影响,由此初步提出了黑龙江省农业地球化学种植区划。  相似文献

易门狮山铜矿床产于元古界昆阳群绿汁江组狮山段泥质、炭质白云岩及粉砂岩中。狮山段由黑色层（Ｍｃ）、过渡层（Ｍｇ）和紫色层（Ｍｐ）组成。在矿床地质特征研究基础上，总结了该矿床的微观规律及其特征（包括化学组分、微量元素在狮山段、矿体中的分配；元素共生组合及演化规律；有机碳的含量与成矿；硫同位素及硫源；矿物包裹体特征等）。提出成矿元素经历了离散、合并、分解和矿体形成的演化过程。  相似文献   

Geochemistry of the Jinman Vein—Type Copper Deposit,Western Yunnan Province,China——I.Element Geochemical Characteristics   总被引：3，自引：0，他引：3  

季宏兵  李朝阳 《中国地球化学学报》1996,15(2):172-184

The Jinman copper deposit,which is situated on the northern margin of the Lanping-Simao back-arc basin,western Yunnan Province,is a silver-bearing,high-grade vein-type copper deposit.Comprehensive element geochemical studies of the host rocks and hydrothermal minerals revealed the regularities in the distribution,mobilization and transport of elements from the host rocks to hydrothermal minerals.In conjunction with the fluid inclusion and isotope data,it is suggested that the ore-forming fluid was derived mainly from a deep source characterized by CO2 enrichment and reduction in nature.It is also suggested that the oreforming materials come largely from a deep source.although the contribution of the country rocks should not be ruled out.It is also found that some hydrothermal minerals are possessed of MREE-enrichment patterns.It is deduced that the REEs in the deep-source ore fluid were transported in the form of CO3^2- complexes and were deposited in a continental basin(or a hot-spring basin).  相似文献   

A Study on the Geological—Geochemical Dynamics of Hydrothermal Ore Deposition as Exemplified by the Muping—Rushan Gold Deposit Belt,Eastern Shandong,China     

赵伦山  高太忠等 《中国地球化学学报》1996,15(4):289-295

This paper presents a method of establishing a hydrothermal ore-forming reaction system.On the basis of the study of four typical hydrothermal deposits,the following conclusions concerning geochemical dynamic controlling during hydrothermal mineralization have been sions concerning geochemical dynaamic controlling during hydrothermal mineralization have been drawn:(1)The regional tectonic activities control the concentration and dispersion of elements in the ore-forming process in terms of their effects on the thermodynamic nature and conditions of the ore-forming reaction system.(2)During hydrothermal mineralization the activites of ore-bearing faults can be divideb into two stages:the brittle splitting stage and the brittle-tough tensing stage,which would create characteristically different geodynamic conditions for the geochemical thermodynamic ore-forming system.(3)The hydrothermal ore-forming reaaction system is an open dynamic system.At the brittle splitting stage the system was so strongly supersaturated and unequilibrated as to speed up and enhance the crystallization and differentiation of ore-forming fluids.And at the brittle-tough tensing stage,the ore-forming system was in a weak supersaturated state;with decreasing temperature and pressure the crystallization of oreforming material would show down,and it can be regarded as an equilibrated state.(4)In the lates stages of hydrothermal evolution,gold would be concentrated in the residual ore-forming solution.The pulsating fracture activite in this stage led to the crush of pyrite ore and it was then filled with gold-enriched solution,forming high-grage“fissure”gold ore.This ore-forming process could be called the coupling mechanism of ore formation.  相似文献
