In the past, most of geochemical parameters were summarized by experience. In order to detect more favou-rable geochemical parameters for deposit prospectings, arbitrary associations of SiO_2, Al_2O_3, Fe_2O_3, FeO, MgO, CaO, Na_2O, K_2O, CO_2, MnO, P_2O_5 and TiO_2 of 30 samples from 17 given diamond-bearing or non-diamond-bearing lamproite bodies at home and abroad are calculated by computer and using the rate of mistake, we examine every association of the parameters.

In the past, most of geochemical parameters were summarized by experience. In order to detect more favou-rable geochemical parameters for deposit prospectings, arbitrary associations of SiO_2, Al_2O_3, Fe_2O_3, FeO, MgO, CaO, Na_2O, K_2O, CO_2, MnO, P_2O_5 and TiO_2 of 30 samples from 17 given diamond-bearing or non-diamond-bearing lamproite bodies at home and abroad are calculated by computer and using the rate of mistake, we examine every association of the parameters. Selected geochemical parameters of lamproite type diamond deposits in which the rate of mistake is less than 6-10 % are MgO/MnO, CaO/TiO_2, SiO_2/(Na_2O+K_2O+CO_2), K_2O/(CO_2+MnO), MgO/(MgO+CaO+K_2O+Na_2O), CaO/(FeO+MgO+CaO), (MgO+MnO)/(Fe_2O_3+FeO+TiO_2) etc.

前人总结的地球化学找矿参数,大多数是作者个人对该矿种地球化学特征的经验性总结,局限性较大。为了探索更有助于找矿的地球化学参数,我们以钾镁煌斑岩型金刚石矿床为例,用计算机对国内外已知含金刚石程度的17个岩体的30件样品中SiO_2、Al_2O_3、Fe_2O_3、FeO、MgO、CaO、NaO、K_2O、CO_2、MnO、P_2O_5、TiO_2共12个分析项目进行了任一组合方式的计算,然后对每一组合参数进行错判率检验,最终选出错判率小于6—10%的钾镁煌斑岩型金刚石矿床地球化学找矿参数为:MgO/MnO、CaO/TiO_2、SiO_2/(Na_2O+K_2O+CO_2)、K_2O/(CO_2+MnO),MgO/(MgO+CaO+K_2O+NO_2O)等22个

A method is developed for the determination of components including Sc, Sn, W, Si,Ti, V, Cr, AJ,Ba, and Sr in galena and sphalerite by ICP-AES.The sample is roasted to eliminate sulfur and partially As,Se,and Te. After decomposition with Na2O2, the melt is dissolved in 1:1 HNO3 containing tartaric acid to inhibit the hydrolysis of W and Sn. Y is used as internal standard to improve precision,the interferences of some elements and background are corrected by coefficients. The method proposed,together with that of the preceding paper, can be used to analyse thirty-three elements in galena and sphalerite.

定义了评价油层的性质参数和丰度的概念,并结合含油级别的描述性定义。用数学中的秩和检验法明确区分了参数的属性问题。本文所指参数来自氯仿沥青“A”、族组成、热解色谱、饱和烃色谱及红外吸收光谱等分析项目。氯仿沥青“A”,热解S_1、S_2、S_1+S_2是评价油层的丰度参数:族组成,热解S_1、S_2/(S_1+S_2),红外吸收光谱各参数,饱和烃色谱各参数等都是评价油层的性质参数。
