“…The rift zone Song Da is one of the important tectonic units squeezed between large tectonic blocks: the South China block and the Indochina block (Takemoto et al 2005). In the Hoà Bình Province the formation reaches the thickness of c. 5000 m. The formation begins with Permian paralic sediments, from which time basalt outcrops originate (Tran et al 2016). The Permian sediments are covered by the lower Triassic sandstones and siltstones.…”

This paper presents a case study from the Hiem cave (Hoà Bình province, North Vietnam) showing how a multidisciplinary approach in archaeological research can develop knowledge on the everyday life of the hunter-gatherer Hoabinhian groups occupying the cave during the early Holocene (8500-8200 cal BC). The archaeological analysis presents the characteristic Hoabinhian artefacts and their usage, while archeozoological, malacological and archaeobotanical research throw light on the way of life, including plant and animal elements of a daily diet as well as the settlement seasonality of the cave.

“…Such time lag was considered in several works [Hoa et al, 2016;etc.]. However, the number of high-precision dates of granitoids from LIPs is limited, and it is not clear whether this time lag is typical of all the LIP in fold areas or it is a special case.…”

Abstract:In large igneous provinces (LIP) of fold areas, granitoid rocks are dominant, while mantle-derivated rocks play a subordinate role in rock formation. If magma emissions are impulsive, it may take 25-30 million years for a LIP to form and take shape. In this paper, we present the results of 40 Ar/ 39 Ar isotopic studies of Permian-Triassic granitoids in the Altai region, Russia, and clarify the evolution of this region located at the periphery of the Siberian LIP. These granitoids are very diverse and differ not only in their rock set, but also in the composition features. In the study region, the granodiorite-granite and granite-leucogranite association with the characteristics of I-and Stypes as well rare metal ore-bearing leucogranites are observed along with gabbro-and syenite-granite series, including mafic and intermediate rocks with the A2-type geochemical features. The 40 Ar/ 39 Ar data obtained in our study suggest that most of the studied granitoids intruded within a short period of time, 254-247 Ma. This timeline is closely related to the formation of granitoids in the Kuznetsk basin and dolerite dikes in the Terekta complex (251-248 and 255±5 Ma, respectively), as well as intrusions of lamproite and lamprophyre dikes of the Chuya complex (245-242 and 237-235 Ma). Thus, we conclude that the Altai Permian-Triassic granitoids are varied mainly due to the evolution of mafic magmatism.Key words: geochronology; Ar/Ar dating; granitoid magmatism; Altai Аннотация: В складчатых областях крупные изверженные провинции (LIP) характеризуются резким преоб-ладанием гранитоидов при подчиненной роли пород мантийного генезиса. Длительность формирования отдельных LIP может достигать 25-30 млн лет при импульсном характере магматизма. В работе конкретизи-руется схема формирования одного из периферических сегментов Сибирской LIP на основе 40 Ar/ 39 Ar изотоп-ных исследований пермотриасовых гранитоидов Алтая, которые резко различны не только по набору пород, но и по особенностям их состава. Наряду с габбро-и сиенит-гранитными сериями, включающими основные и средние породы с геохимическими характеристиками пород A2-типа, на этом рубеже проявлены гранодио-рит-гранитные и гранит-лейкогранитные ассоциации с характеристиками I-и S-типа, а также рудоносные редкометалльные лейкограниты. Результаты 40 Ar/ 39 Ar датирования свидетельствуют о том, что внедрение большинства изученных интрузий гранитоидов Айского, Теранжикского, Тархатинского, Белокурихинского и Синюшенского массивов, Точильненского и Осокинского штоков-сателлитов произошло в короткий проме-жуток времени -254-247 млн лет. Фиксируется достаточно тесная временная связь формирования гранито-идов с формированием траппов Кузнецкого бассейна и долеритовых даек терехтинского комплекса (251-248 и 255±5 млн лет соответственно), с внедрением даек лампроитов и лампрофиров чуйского комплекса (245-242 и 237-235 млн лет). Таким образом, разнообразие пермотриасовых гранитоидов Алтая определяется, в первую очередь, эволюцией базитового магматизма. GEODYNAMICS & TECTONOPHYSIC...
