【摘要】：本文在系統(tǒng)收集并分析前人地質(zhì)資料與成果的基礎(chǔ)上,通過(guò)1:50000的水系沉積物測(cè)量工作和1:10000的土壤測(cè)量工作,從水系沉積物和土壤地球化學(xué)特征入手,探討了元素分布、分配特征,研究了元素的組合、單元素異常及綜合異常分布特征,并結(jié)合地質(zhì)背景進(jìn)行了異常解釋推斷,對(duì)區(qū)域成礦潛力進(jìn)行了預(yù)測(cè)。通過(guò)1:50000水系沉積物測(cè)量共圈定以Au為主的6處異常,其中Hs-乙-1、Hs-乙-2綜合異常元素組合套合較好,異常濃度分帶較明顯,找礦潛力較大。通過(guò)1:10000土壤測(cè)量共圈定單元素異常194處,其中Au元素42處、Ag元素18處、Cr元素28處、Cu元素21處、Fe元素10處、Mn元素12處、Ni元素29處、Sb元素10處、Zn元素24處;元素組合異常50處,其中Au、Ag、Sb、Cu、Zn元素組12處,Cr、Ni元素組31處,Fe、Mn元素組7處;元素綜合異常33處,其中乙類異常5處,丙類異常19處,丁類異常9處。在綜合研究的基礎(chǔ)上,共圈定2個(gè)找礦靶區(qū)。通過(guò)1:50000水系沉積物測(cè)量工作和1:10000土壤測(cè)量工作,本人認(rèn)為該區(qū)主要成礦元素為Au、Cu、Ni、Fe,其中Au、Cu元素的分布在中酸性侵入巖中,與構(gòu)造斷裂有較大的關(guān)系,Ni、Fe元素主要要分布在拉果錯(cuò)蛇綠巖帶中的超基性巖中,與構(gòu)造有一定的關(guān)系。在上述研究的基礎(chǔ)上,分析了成礦潛力,劃分了成礦遠(yuǎn)景區(qū),圈定了找礦靶區(qū),為拉果錯(cuò)地區(qū)提供了比較豐富的地球化學(xué)資料。
[Abstract]:Based on the systematic collection and analysis of previous geological data and results, this paper discusses the distribution of elements from the geochemical characteristics of water system sediment and soil through the work of 1: 50000 water system sediment survey and 1: 10000 soil survey.The distribution characteristics of element combination, single element anomaly and integrated anomaly distribution are studied, and the anomaly interpretation and inference are made in combination with geological background, and the regional metallogenic potential is predicted.Six anomalies, mainly au, were delineated by 1: 50000 water system sediment survey. Among them, Hs-eth-1hs-2 complex anomaly elements combined well, the anomalous concentration zonation was obvious, and the prospecting potential was great.194 anomalous elements of common circle order were measured by 1: 10000 soil. Among them, 42 places of au element, 42 place of silver element, 18 place of Cr element, 28 place of cr element, 21 place of Cu element, 21 place of iron element, 10 place of mn element element, 29 place of Ni element element, 29 place of Sb element element, 10 place of Zn element, 50 places of element combination anomaly,Among them, there are 12 sites in the element group of Augna AgSbSbSbCU Zn, 31 in group Ni, 31 in the element group and 7 in the group of FeMN, among which there are 33 Synthetical anomalies, among which 5 are abnormal in Group B, 19 in Group C and 9 in Group D.On the basis of comprehensive study, two prospecting targets were delineated.Through 1: 50000 water system sediment survey and 1: 10 000 soil survey, I believe that the main metallogenic elements in this area are Au-CuCU Nianfen Fe, in which the Au-Cu element is distributed in intermediate-acid intrusive rocks.There is a great relationship with structural faults and the elements of NiNII Fe are mainly distributed in the ultrabasic rocks in the Lago Oro ophiolite belt, and are related to the structure to a certain extent.On the basis of the above research, the metallogenic potential is analyzed, the metallogenic area is divided and the prospecting target area is delineated, which provides abundant geochemical data for the Lago Cuo area.
