:遂寧2098-DSD-150-SE羅克韋爾AB伺服驅(qū)動器價格二里頭遺址的鑄銅遺存和冶金是早期青銅文化的重要研究對象。本文基于二里頭遺址歷年發(fā)現(xiàn)的鑄銅遺存,結(jié)合聚落形態(tài)的變化,探討該遺址的冶鑄點(diǎn)和作坊,并對鑄銅作坊的范圍、主要遺跡和年代進(jìn)行討論。認(rèn)為目前尚未有明確證據(jù)表明二里頭文化期存在鑄銅作坊,第二期早段的時候存在著分散的冶鑄點(diǎn),第二期晚段至第四期早段,冶鑄活動主要集中在鑄銅作坊之內(nèi),二里頭文化第四期晚段以后,冶鑄點(diǎn)再次呈現(xiàn)分散的特點(diǎn)。鑄銅作坊的面積超過15平方米,其使用年代應(yīng)為第二期早段至第四期晚段。
