Outline of Annual Research Achievements |
本科研の最終年度にあたる平成27年度は,前年までの調査により得られた結果を踏まえ,1)タイ北部のスコタイ帯におけるペルム-三畳系(特にP-T境界炭酸塩サクセッションの層序と化石群衆変遷),2)スコタイ帯西縁に分布する蛇紋岩体,3)ラオス北部ウドムサイ地域でのスコタイ帯延長部,4)ラオス北部パックベン地域でのナン縫合線延長部,での調査を中心に,タイ北部のチェンライ-ランパン地域およびラオス北部のパックベン-ウドムサイ地域で野外調査を行った.2回の調査で,日本からは計7名を派遣した. タイ北部の調査では,前年度までに予備調査を行ったペルム-三畳系炭酸塩サクセッションにおいて,最後期ペルム紀有孔虫群集を含む生砕性石灰岩に,最前期三畳紀のPostcladella kalhori群集を伴うドロマイト岩~ドロマイト質石灰岩が直接累重することを確認した.これは,東南アジアでは初の,炭酸塩岩サクセッションにおけるP-T境界である.またスコタイ帯の調査では,その西縁に蛇紋岩が分布することを確認した.スピネルの化学分析からは,この蛇紋岩が海洋底起源のかんらん岩に由来することが示された. ラオス北部の調査では,ウドムサイ南西地域においてメガロドンを産する石灰岩と,凝灰質砕屑岩からなる三畳系が広く分布することを確認した.これらの三畳系は,従来の地質図では石炭-ペルム系とされていた.岩相と年代から,ウドムサイ地域の三畳系はタイ北部,スコタイ地域のHong Hoi層及びDoi Long層に対比可能である.一方パックベン地域の蛇紋岩体で得られた試料の化学分析からは,それがタイ北部のナン縫合線に分布する超塩基性岩,蛇紋岩体同様,島弧マントル起源であるというデータが得られた. さらに,本科研で得られた結果を国内外の研究集会(特に本科研メンバーが中心となっているIGCP589のシンポジウム)において発表した.また,同時に公表論文の作成を進めた.
