| 中文摘要: |
| 2025年新疆地质研究院在西准噶尔哈图金矿以东一带石英闪长岩中发现了金矿体。地表延伸长90 m，厚1.42 m，平均品位2.58 g/t，顶板岩性为石英闪长岩，底板岩性为硅化褐铁矿化凝灰岩。矿石结构为粒状结构、碎裂结构和交代结构，矿石构造为块状构造和浸染状构造。矿石矿物为黄铁矿、赤铁矿、白钛矿和褐铁矿，脉石矿物为斜长石、石英、白云母、白云石和绢云母等。围岩蚀变主要为硅化、褐铁矿化、碳酸盐化、绢云母化、白云石化、绿帘石化、绿泥石化。大比例尺岩石地球化学测量和高精度地球物理测量显示，矿体（岩体）与Au、As、Sb、W异常对应性很好，岩体具中高极化率、低电阻率特征，在地表以下250～550 m的空间内可能存在隐伏岩体。该金矿体具备斑岩型矿床的基本特征，深部勘查前景良好。 |
| 英文摘要: |
| In 2025， Xinjiang Academy of Geology discovered gold ore bodies within quartz diorite in the area east of the Hatu gold deposit， West Junggar. The ore body extends for 90 meters along the surface with a thickness of 1.42 meters and an average grade of 2.58 g/t. The hanging wall is quartz diorite， while the footwall consists of silicified and limonitized tuff. The ore textures are mainly granular， cataclastic， and metasomatic， and the ore structures are massive and disseminated. Ore minerals include pyrite， hematite， leucoxene， and limonite. Gangue minerals are primarily plagioclase， quartz， muscovite， dolomite， and sericite. Wall rock alterations are dominated by silicification， limonitization， carbonatization， sericitization， dolomitization， epidotization， and chloritization. Large-scale rock geochemical surveys and high-precision geophysical surveys indicate that the ore body （rock body） corresponds well with Au， As， Sb， and W anomalies. The rock body exhibits characteristics of medium-high chargeability and low resistivity， suggesting the possible existence of a concealed rock body in the space between 250 and 550 meters below the surface. This gold ore body possesses the basic characteristics of a porphyry deposit and holds promising prospects for deep exploration. |
