地表典型铁锰沉积物岩石漆的研究历程与展望

Research History and Prospects of Rock Varnish,Most Representative Terrestrial Fe/Mn-rich Sediment

岩石漆是地表风化环境中最具代表性的铁锰质沉积物,一直以来在学界广受关注。近几十年来,随着表征技术的不断发展,岩石漆的研究也取得了显著成果。简述了岩石漆的研究历程,着重介绍了岩石漆的形貌特征、地球化学特征、矿物组成和成因机制。产于地表暴露环境中的岩石漆是地表关键带的重要组成部分,是各种物质发生交互作用的关键性场所。因此,岩石漆具有记录环境、影响环境和改变环境的能力,在反演环境气候变化、定年上古遗迹、参与地表物质演化、探索地外生命等方面具有重要的研究意义。

Rock varnish is the most representative Fe/Mn-rich sediment in terrestrial weathering environment,which has attracted great research interest for a long time.During the past few decades,research of rock varnish has achieved great process with continuous development of characterization methods.The research history of rock varnish was summarized,and its morphological features,geochemical characteristics,mineral component and formation hypotheses wers introduced in detail.Rock varnish is an important part of Earth Critical Zone,at which the interaction between different substances happened.Therefore,rock varnish has the capability of recording,influencing and changing the environment,and possess much significance in historical climate change research,ancient relics dating,surface substance evolution and extraterrestrial life exploration.
