纳塔尔卡脉金矿床，又称马特罗索夫金矿，位于俄罗斯东北部马加丹地区，北纬61°39‘，东经147°50’，于1943年发现，1945年投产。该矿已生产超过75吨黄金，平均品位为4克/公吨，储量约为450公吨。纳塔尔卡矿床沿Yana-Kolyma成矿带西南翼产出，赋存于主要的NW向Tenka断裂中。矿床赋存于上二叠统碳质沉积中，经历了绿片岩变质作用。矿带沿着一条Z形的走滑断裂带产出，该断裂带延伸约12至13公里。从平面图上看，矿带西北部长约5公里，宽100~200m，中部宽350~400m，东南段宽600m。矿石矿物主要为毒砂和黄铁矿，占硫化物的95%左右，其次为磁黄铁矿、钴镍矿等。
The Natalka lode gold deposit, also known as the Matrosov mine, is located in the Magadan region of northeastern Russia at 61° 39′ N, 147° 50′ E. The deposit was discovered in 1943 and production started in 1945. The mine has produced more than 75 metric tons of gold, with an average grade 4 g/metric ton (mt), and has reserves of about 450 mt. The Natalka deposit occurs along the southwestern flank of the Yana-Kolyma metallogenic belt and is confined to the major, NW-trending Tenka fault. The deposit is hosted by Upper Permian carbonaceous sediments, subjected to greenschist metamorphism. The ore zones occur along a Z-shaped, strike-slip fault zone that extends for about 12 to 13 km. In plan view, the ore zones are about 5 km long and 100 to 200 m wide in the northwest portion, 350 to 400 m wide in the central portion, and 600 m wide in the southeast portion of the deposit. The main ore minerals are arsenopyrite and pyrite, which comprise about 95% of the sulfides, along with subordinate pyrrhotite, Co-Ni...
