반암동 광화작용이 수반된 관입암체로 이루어진 촉트체치 지역은 몽골 남부 중앙아시아 조산대의 구르반사이한 호상열도 지형에 위치한다. 이러한 촉트체치 지역에서 예비조사를 수행하였다. 촉트체치 지역의 동 광화작용은 페름기에 관입한 알칼리 화강암과 관련된 반암동 광상이다. 공작석이 산출되는 알칼리 화강암 지역에서 프로필리틱 변질대가 넓게 분포한다. 편광현미경에서 확인된 광석광물은 자철석, 황철석, 반동석이다. 프로필리틱 변질대 시료에서는 석영, 견운모, 녹니석, 녹렴석 등이 관찰되었다. XRD와 SEM-EDS 분석 결과 동 광물은 주로 공작석과 적동석으로 이루어진다. 공작석 산출지에서 채취한 시료의 평균 동 함량은 759 ppm이고 최대 동 함량은 6190 ppm이다. 촉트체치 지역의 광화작용 특성은 촉트체치 지역으로부터 남쪽으로 56 km 떨어진 오유 톨고이 동-금(-몰리브덴) 광상 및 북동쪽으로 120 km 떨어진 차간 수바르가 동-몰리브덴 광상과 유사하다. 조사지역의 지질, 지구조 환경, 암상, 광물, 변질 등이 다른 반암동 광상과 유사한 특성을 갖는다. 따라서 촉트체치 동 광화 지역에 대해 지하 광체 확인을 위한 IP 탐사를 포함한 추가 광물자원 탐사가 필요하다.

Abstract ▼ AI-Helper

Tsogttsetsii area, an intrusive complex associated with Cu porphyry mineralization, is located in the Gurvansaikhan island arc terrane of the Central Asian Orogenic belt, Southern Mongolia. We performed a reconnaissance survey in Tsogttsetsii area. Cu mineralization in Tsogttsetsii area is porphyry Cu type related with alkali granite intruded in Permian. Mineralogical and textural properties of the ores and associated minerals were analyzed using X-ray diffraction, thin section petrography, and Scanning electron microscopy-Energy dispersive spectroscopy (SEM-EDS). Ore minerals identified in polarizing microscope are magnetite, pyrite and bornite. Propylitic alteration zone occurs broadly in the area where malachite occurrences are shown to be spread intensively in alkali granite area. Quartz, sericite, chlorite and epidote were observed in the alteration zone samples. As results of XRD and SEM-EDS analysis, samples of copper oxides were composed mainly of malachite, cuprite and small amounts of quartz. Average and maximum Cu contents of samples collected from malachite occurrences area are 759 ppm and 6190 ppm, respectively. The characteristics of mineralization in Tsogttsetsii area is similar to Oyu Tolgoi Cu-Au (Mo) deposit and Tsagaan Suvarga Cu-Mo deposit which are 56 km south and 120 km northeast from Tsogttsetsii area, respectively. Characteristics of the study area, such as the geology, tectonic environment, lithology, mineralization, and alterations of the rocks within the survey area, resemble the characteristics of other porphyry deposits. Therefore further exploration including Induced Polarization (IP) survey for identifying subsurface orebody is required.

문제 정의

In this region, the KIGAM and MRAM teams conducted a geological survey of the surface rocks in June and August of 2015. The goal of this study in the Tsogttsetsii area is to verify the presence and size of the deposits estimated by previous studies and to collect samples from these areas to estimate properties of the prospects.

제안 방법

Sample analysis was performed using an EDS system (Oxford Instruments, Abingdon, UK). Analyses were conducted with an accelerating voltage of 20 kV and a 10 mm working distance.
The three most common modes of operation in SEM analysis are backscattered electron imaging (BSE), secondary electron imaging (SEI), and EDS. In this study, SEM-EDS analysis was performed on samples GPS567, GPS569, TS-17, TS-34, and TS-35. The images and respective graphs, which illustrate abundances of elements, of each sample are shown in Fig.
5). The main components of the survey area were analyzed for ten major elements (SiO₂, TiO₂, Al₂O₃, Fe₃O₂, MnO, CaO, Na₂O, K₂O, and P₂O₅) using an XRF and an inductively coupled plasma-optical release spectrometry (ICP-OES), which is an analytical method for the determination of elements (such as Cu, Pb, Zn, Zr, Nb, Hf, Ta, As, Bi, Co, Cr, Ni, Rh, and Vi).

대상 데이터

For this study, twelve petrographic thin sections were made from the field samples (Fig. 8). They are comprised predominantly porphyritic in texture, fine to medium-grained, and consist mainly of plagioclase, orthoclase, quartz, hornblende, biotite, and accessory titanite, apatite, opaque minerals, and rare zircon.
The survey area is a rectangular block that measures 2.5 km × 1 km.

성능/효과

The peaks of quartz were the most evident at all samples of the study sites. The results show that GPS567 contains montmorillonite and malachite [Cu₂(OH)₂CO₃]; GPS569 contains cuprite [Cu₂O], Libethenite [Cu₂PO₄OH] and Leisingite; TS-17 contains marshite[CuI], and Donpeacorite [(Mn,Mg)MgSi₂O₆]; and TS-34 contains laumontite.
