阿尔恰勒铅锌矿产于下石炭统阿克沙克组灰岩中，铅锌矿体呈层状富厚矿体产出。铅同位素组成表明该矿床的铅可能主要来源于造山带，硫同位素组成显示硫来源于地幔或地壳深部，氢氧同位素反映出成矿流体具有大气降水加入的特征，包裹体特征为中温成矿和低盐度流体。该矿床属于层控矿床，为喷流沉积改造富集形成的矿床，并建立了成矿模式。
阿爾恰勒鉛鋅礦產于下石炭統阿剋沙剋組灰巖中，鉛鋅礦體呈層狀富厚礦體產齣。鉛同位素組成錶明該礦床的鉛可能主要來源于造山帶，硫同位素組成顯示硫來源于地幔或地殼深部，氫氧同位素反映齣成礦流體具有大氣降水加入的特徵，包裹體特徵為中溫成礦和低鹽度流體。該礦床屬于層控礦床，為噴流沉積改造富集形成的礦床，併建立瞭成礦模式。

Aerqiale Pb-Zn deposit occurs in limestone of Akeshake Formation, Lower Carboniferous, with occurrence of enriched Pb-Zn ore body. The composition of Pb isotope indicates that most Pb in the deposit originates from oro-genic belt;the composition of sulfur isotope indicates that most S originates from mantle and deep crust;hydrogen and oxygen isotope shows that mineralizing fluid is characterized by atmospheric precipitation and the inclusions are inter-mediate temperature mineralized and low salinity fluid. The deposit is strata-bound deposit, which is reformed through sedimentation-exhalation concentration. Hence the metallogenic model is determined.
