元江镍矿区硫化镍矿床找矿思路探讨 - Substance of rock - forming and ore - forming in both jianchaling and jinchuan nickel deposit mainly derived from the upper mantle , but the former source is relatively depleted mantle . on the other hand , there exsisted the crustal contamination during the formation of the two mineral deposits , the later contaminated poorly and gave priority to deep contamination . ( 5 ) by the comparative study of jianchaling with jinchuan nickel sulflde deposit , it is pointed that small basic - ultralbasic complexes which dis
( 5 )通过对煎茶岭和金川镍矿床的比较研究，结合对国内外有关岩浆镍矿床的比较分析，根据我国的地质特点，提出沿较老地块边缘分布的特别是沿华北地块北缘分布的基性?超基性小杂岩体，是找寻大而富的硫化镍矿床之有利找矿方向；而对较老地块内部的镁铁质侵入体，亦应给予高度注意。 - According to the theory and study methods of comparative economic geology , the ore - forming geological background , geological feature , the elements geochemistry , the metallogenic geochronology about the two ore deposits and rock - bodys are systematic analysed , compared , and researched by means of new measure and assay technique . jianchaling nickel sulflde deposit is stress investigated in order to study similarities and differences between the two deposits in mineralization background , geochimistry , and metallogenesis , also to find the reasons for these , discuss the regularity of formation and distribution for the type deposit , and guide its exploration
本次工作依据比较矿床学的研究思路，在重点剖析煎茶岭镍矿床成矿地质、地球化学特征的基础上，采用新的分析测试技术手段，对这两个岩浆硫化镍矿床从成矿地质背景、岩体及矿床地质特征、地球化学及成矿作用年代学等角度进行系统分析、比较和研究，找出二者的共同性和差异性，进一步更深刻地认识其成因并探讨该类矿床形成与分布的规律性以指导找矿。 - According to the features of naphthenic base oil ( i . e . , high nitrogen and low sulfur content ) and based upon theoretical analysis of the h2s concentration needed for phase equilibrium of nickel sulfide and tungsten sulfide in hydrogen , the most economic quantity of sulfiding agent injected into the reactor for supplement of sulfur in lube oil hydrogenation catalysts was obtained
摘要针对环烷基油高氮、低硫的特点，通过对硫化钨和硫化镍在氢气中相平衡态所需硫化氢浓度的理论分析，对反应器入口所需补硫量作了详细的阐述，得出了最经济的补充注硫量。
