103 Elucidating the petrogenesis and geodynamic setting(s) of anorthosites in Archean layered 104 intrusions and Tethyan ophiolites has significant implications for crustal evolution and growth 105 throughout Earth history. Archean anorthosite-bearing layered intrusions occur on every continent. 106 Tethyan ophiolites occur in Europe, Africa, and Asia. In this contribution, the field, petrographic, 107 petrological, and geochemical characteristics of 100 Tethyan anorthosite-bearing ophiolites and 108 155 Archean anorthosite-bearing layered intrusions are compared. Tethyan anorthosite-bearing 109 ophiolites range from Devonian to Paleocene in age, are variably composite, contain anorthosites 110 with highly calcic (An44-100) plagioclase and magmatic amphibole. These ophiolites formed 111 predominantly at convergent plate margins, with some forming in mid-ocean ridge, continental 112 rift, and mantle plume settings. The predominantly convergent plate margin tectonic setting of 113 Tethyan anorthosite-bearing ophiolites is indicated by negative Nb and Ti anomalies and magmatic 114 amphibole. Archean anorthosite-bearing layered intrusions are Eoarchean to Neoarchean in age, 115 have megacrystic anorthosites with highly calcic (An20-100) plagioclase and magmatic amphibole 116 and are interlayered with gabbros and leucogabbros and intrude pillow basalts. These Archean 117 layered intrusions are interpreted to have predominantly formed at convergent plate margins, with 118 the remainder forming in mantle plume, continental rift, oceanic plateau, post-orogenic, 119 anorogenic, mid-ocean ridge, and passive continental margin settings. These layered intrusions 120 predominantly crystallized from hydrous Caand Al-rich tholeiitic magmas. The field, 121 petrographic and geochemical similarities between Archean and Tethyan anorthosites indicate that 122 they were produced by similar geodynamic processes mainly in suprasubduction zone settings. We 123 suggest that Archean anorthosite-bearing layered intrusions and spatially associated greenstone 124 belts represent dismembered subduction-related Archean ophiolites. 125

含特提斯斜长岩的蛇绿岩与含太古代斜长岩层状侵入体的比较：对太古代地球动力学过程的影响

103 阐明太古代层状 104 侵入体和特提斯蛇绿岩中斜长岩的岩石成因和地球动力学环境对整个地球历史的地壳演化和生长具有重要意义 105。含太古代斜长岩的层状侵入体发生在每个大陆上。106 特提斯蛇绿岩产于欧洲、非洲和亚洲。在这篇文章中，比较了 100 块含特提斯斜长岩蛇绿岩和 108 155 块太古代含斜长岩层状侵入体的野外、岩相、107 项岩石学和地球化学特征。含特提斯斜长岩的 109 蛇绿岩年龄从泥盆纪到古新世不等，复合程度不一，含有具有高钙（An44-100）斜长石和岩浆角闪石的斜长岩 110。这些蛇绿岩 111 主要形成于会聚板块边缘，一些形成于大洋中脊、大陆 112 裂谷和地幔柱环境。113 个含特提斯斜长岩的蛇绿岩的主要会聚板块边缘构造环境由负的 Nb 和 Ti 异常以及岩浆 114 角闪石指示。含太古宙斜长岩的层状侵入体年龄为始太古代至新太古代，115 有巨晶斜长岩，高钙（An20-100）斜长石和岩浆角闪石116，并夹有辉长岩和白长岩，侵入枕状玄武岩。这些太古代 117 层状侵入体被解释为主要形成于会聚板块边缘，其余 118 形成于地幔柱、大陆裂谷、大洋高原、造山后、119 造山带、大洋中脊和被动大陆边缘环境。这些层状侵入体120主要从含水Ca和富含铝的拉斑岩浆结晶。该领域，太古宙和特提斯斜长岩之间的 121 个岩石学和地球化学相似性表明，122 个它们是由主要在超俯冲带环境中的类似地球动力学过程产生的。我们 123 认为含有太古代斜长岩的层状侵入体和空间相关的绿岩 124 带代表了与俯冲相关的太古代蛇绿岩的肢解。125 我们 123 认为含有太古代斜长岩的层状侵入体和空间相关的绿岩 124 带代表了与俯冲相关的太古代蛇绿岩的肢解。125 我们 123 认为含有太古代斜长岩的层状侵入体和空间相关的绿岩 124 带代表了与俯冲相关的太古代蛇绿岩的肢解。125
