据Mining.com网站报道，澳大利亚研究人员对数十年来的地质理论提出挑战，他们认为世界最富硬岩锂矿床形成深度可能比原先想象的要大。

由科廷大学(Curtin University)和西澳地质调查所(Geological Survey of Western Australia，GSWA)为首的团队取得的这项突破证明这些矿床接近于地幔，而非地表。

此发现将改变全球如何以及在何处寻找锂矿床的思路，也正值这种用于电动汽车、智能手机和可再生能源存储系统所需电池的关键矿产需求快速上升之际。

本项成果第一作者、科廷大学地学院和GSWA地质学家胡戈·史密斯(Hugh Smithies)称，此发现为探索锂矿成因提供了新思路。这项研究发现，富锂岩浆似乎形成于幔源熔融体再熔融期间，并以深大断裂为通道，富集在古老地壳岩石中。

“将深部幔源岩浆同富集壳源关联有助于解释为什么西澳古地体缺少被认为是锂成矿必需的沉积岩石却拥有一些世界最大锂矿床”，史密斯称。“这扩大了以前被忽视地区的找矿潜力”。

西澳州锂产量已经占到世界的35%，是排在第二位的智利产量的1.5倍。

其中大多数产量来自伟晶岩，一种在西澳州太古代地体常见的粗粒火成岩，与皮尔巴拉和伊尔冈地区一样，其年龄超过25亿年。

虽然大多数硬岩锂来源于同样的地层，但目前的勘探模型都是基于较为年轻的地质系统。GSWA的研究对这些模型提出了挑战，表明太古代锂成矿系统有自身的规律并依赖地球深部过程的独特背景。

新发现表明，太古代成锂系统因地区各异，而且需要独特的矿床地质背景。

这项研究发现发表于《自然》杂志，时点正当。因为锂需求持续上升，作者认为新认识将白改变勘探战略——不仅仅在西澳，而是全球。
