【摘要】：本次論文是以對(duì)內(nèi)蒙古自治區(qū)烏拉特后旗呼和沙拉地區(qū)白云巖礦資源調(diào)查為素材完成的。依據(jù)市場(chǎng)目前對(duì)白云巖礦及其產(chǎn)品的供需關(guān)系可知目前白云巖礦處于供不應(yīng)求的局面;從地質(zhì)勘探找礦角度審視選區(qū),該區(qū)位于良好的非金屬礦成礦帶上。因此選擇了該區(qū)對(duì)白云巖礦資源進(jìn)行調(diào)查。在本次資源調(diào)查過程中,綜合運(yùn)用了地質(zhì)測(cè)量、綜合剖面測(cè)量、槽探揭露、鉆探運(yùn)用等多種手段對(duì)區(qū)內(nèi)白云巖礦體進(jìn)行了驗(yàn)證性控制、研究。通過本次調(diào)查,在區(qū)內(nèi)發(fā)現(xiàn)并初步控制白云巖礦體四條,編號(hào)分別為I、II、III、IV;其中I號(hào)礦體長(zhǎng)近3000m,平均厚度為97m;II號(hào)礦體長(zhǎng)度近1623m,平均厚度為104m;III號(hào)礦體長(zhǎng)度近660m,平均厚度為26m;IV號(hào)礦體長(zhǎng)度近250m,礦體平均厚度為22.3m。通過本次調(diào)查,經(jīng)過對(duì)區(qū)內(nèi)白云巖成礦環(huán)境以及成礦背景進(jìn)行系統(tǒng)的研究、分析,取得了以下幾點(diǎn)認(rèn)識(shí):1.經(jīng)綜合對(duì)比分析確定:區(qū)內(nèi)白云巖礦體為淺海相沉積變質(zhì)型白云巖礦床;2.通過本次調(diào)查研究發(fā)現(xiàn),區(qū)內(nèi)白云巖礦體均呈厚層狀分布于中元古界渣爾泰群書記溝組地層中,與白云母石英片巖、絹云母石英片巖呈互層狀分布,礦體與圍巖呈整合接觸;3.通過對(duì)區(qū)內(nèi)礦體成礦環(huán)境的分析,確定區(qū)內(nèi)白云巖礦體的找礦標(biāo)志有:地層標(biāo)志、巖石組合標(biāo)志、化探異常指示、赤鐵礦化指示以及構(gòu)造影響等幾個(gè)方面;4.在對(duì)區(qū)內(nèi)白云巖礦體綜合分析的基礎(chǔ)上,推斷出了區(qū)內(nèi)礦體的334?資源/儲(chǔ)量為:100792084.15噸。
[Abstract]:This paper is based on the investigation of dolomite resources in Houqi Huhe Shala area of Inner Mongolia Autonomous region. According to the relationship between supply and demand of dolomite ore and its products in the market at present, dolomite ore is in short supply, and the district is located in a good metallogenic belt from the point of view of geological exploration and prospecting. Therefore, this area is selected to investigate dolomite resources. In the process of resource investigation, geological survey, comprehensive profile survey, trough exploration and exploration, drilling and other methods are used to verify the control of dolomite ore body in this area. Through this investigation, four dolomite ore bodies were discovered and preliminarily controlled in the region. The length of ore body I is about 3000m, the average thickness of orebody I is 97mg, the length of orebody II is 1623m, the length of ore body is 104mLi III is nearly 660m, the average thickness is 26mGIV is about 250m, the average thickness of orebody is 22.3 mm. Through this investigation, the metallogenic environment and metallogenic background of dolomite in this area are systematically studied, and the following understandings are obtained: 1. 1. It is determined by comprehensive comparative analysis that the dolomite orebody in this area is a metamorphic dolomite deposit of shallow marine facies. Through this investigation, it is found that dolomite orebodies in the area are all distributed in thick layers in the middle Proterozoic Jar Tai Group in the Xiangou formation, with interbedded distribution with Muscovite quartz schist and sericite quartz schist, and the ore body and surrounding rock are in integrated contact with each other. By analyzing the metallogenic environment of ore bodies in this area, it is determined that the prospecting marks of dolomite orebodies in this area are stratigraphic markers, rock assemblage markers, geochemical anomaly indicators, hematitization indicators and tectonic effects. Based on the comprehensive analysis of dolomite orebodies in the area, the 334? Resources / reserves are 1: 100792084.15 tons.
