| 1 | The role of magmatism in the thinning and breakup of the South China Sea continental margin显示文摘INTRODUCTION Magmatism plays a key role in the process of continental margin breakup and ocean formation.Even in the extremely magma-poor Iberia and Newfoundland margin,studies of field outcrops have shown that syn-rift magmatism had participated in rifting from a very early stage and contributed directly to the rifting process.The final transition from exhumed continental mantle to the ocean formation is also triggered by the accumulation and eruption of magma[1]. | Zhen Sun Jian Lin Ning Qiu Zhimin Jian PinXian Wang Xiong Pang Jinyun Zheng Benduo Zhu | 2019 | National Science Review2019，6，5： | 34 |
| 2 | Distribution characteristics of seamount cobalt-rich ferromanganese crusts and the determination of the size of areas for exploration and exploitation显示文摘In 2001,the International Seabed Authority (ISBA) initiated the consideration relating to the Regulations for Prospecting and Exploration for Hydrothermal Polymetallic Sulphides and Cobalt-rich Ferromanganese Crusts in the Area at its 7th session.Since then,the consideration of the Regulations has been mainly focused on the size of areas to be allocated for exploration and exploitation of the crusts.This paper,based on the investigation data and the analysis of the distribution characteristics of the crusts,suggests a model for determining the size of areas for exploration and exploitation of the crusts,taking into account various factors such as production scale,crust thickness and grade,mineable area proportion,recovery efficiency,exploration venture,and so on.Through the modeling, the paper suggests that the exploration area (the area covered by each application for approval of a plan of work for exploration of cobalt-rich crusts) shall be 4 856 km 2 and the exploitation area (the mine site area) shall be 1 214 km 2,for 20 years of 1 million wet tonnes annual production. | HE Gaowen MA Weilin SONG Chengbing YANG Shengxiong ZHU Benduo YAO Huiqiang JIANG Xunxiong CHENG Yongshou | 2011 | Acta Oceanologica Sinica2011，30，3： | 9 |

| 5 | Distribution and Classification of Cobalt-Rich Crust显示文摘Based on the on the spot investigation and related data, cobalt rich crust is mainly distributed in the low latitude area near the equator, mostly within 20°S to 20°N, especially 5°-15°(S and N). The analysis of the microtopographic and microphysicognomy features shows that crusts are often present in the complicated topographic regions such as seamount slopes, convex parts of seamounts and joint faults, of which the ideal region is seamount slopes in water depth of 1 500-2 500 m. The authors analyze the relation of the crusts and their bedrock, bedrock type, crust thickness and occurrence, and then attempt to classify the crusts as different types. | Liang Dehua Zhu Benduo Guangzhou Marine Geological Survey, Guangzhou 510075 | 2000 | Journal of Earth Science2000，19，2： | 0 |
| 6 | Formation of the Zengmu and Beikang Basins,and West Baram Line in the southwestern South China Sea margin显示文摘The Zengmu and Beikang basins,separated by the West Baram Line(WBL)in the southwestern South China Sea margin,display distinct geological and geophysical features.However,the nature of the basins and the WBL are debated.Here we explore this issue by conducting the stratigraphic and structural interpretation,faults and subsidence analysis,and lithospheric finite extension modelling using seismic data.Results show that the WBL is a trans-extensional fault zone comprising normal faults and flower structures mainly active in the Late Eocene to Early Miocene.The Zengmu Basin,to the southwest of the WBL,shows an overall synformal geometry,thick folded strata in the Late Eocene to Late Miocene(40.4-5.2 Ma),and pretty small normal faults at the basin edge,which imply that the Zengmu Basin is a foreland basin under the Luconia and Borneo collision in the Sarawak since the Eocene.Furthermore,the basin exhibits two stages of subsidence(fast in 40.4-30 Ma and slow in 30-0 Ma);but the amount of observed subsidence and heat flow are both greater than that predicted by crustal thinning.The Beikang Basin,to the NE of the WBL,consists of the syn-rift faulted sub-basins(45-16.4 Ma)and the post-rift less deformed sequences(16.4-0 Ma).The heat flow(~60 mW/m2)is also consistent with that predicted based on crustal thinning,inferring that it is a rifted basin.However,the basin shows three stages of subsidence(fast in 45-30 Ma,uplift in 30-16.4 Ma,and fast in 16.4-0 Ma).In the uplift stage,the strata were partly folded in the Late Oligocene and partly eroded in the Early Miocene,which is probably caused by the flexural bulging in response to the paleo-South China Sea subduction and the subsequent Dangerous Grounds and Borneo collision in the Sabah to the east of the WBL. | Bing HAN Zhongxian ZHAO Xiaofang WANG Zhen SUN Fucheng LI Benduo ZHU Yongjian YAO Liqiang LIU Tianyue PENG Genyuan LONG | 2023 | Journal of Oceanology and Limnology2023，41，2： | 0 |
