高分辨率啁啾介绍并且 coring 揭示一伸长(ca。400 km ) Holocene Zhujiang 河(珀尔河) 导出泥区域(最大的厚度 > 20 m ) 从 Zhujiang 河三角洲延长,离开广东海岸向西南,到 Leizhou 半岛。二 depo 集中,近似的 depo 集中和 depo 集中远侧,被识别。在离开西方广东省的大陆人架上,泥在比 50 m 浅的水深度被扔;当时到 Zhujiang 河河口的东南,泥区域能延长到 120 m 深线。有 stratigraphic 的联合分析在西方的和平的边缘的海另外的泥泞存款定序(主要 Changjiang (Yangtze ) 和河导出的 Huanghe (黄)) 显示 Zhujiang 河泥泞存款的开始能进一步被划分成二个阶段:舞台 1 在 mid-Holocene 前海平面的 highstand (ca。7.0 cal。ka BP ) ,近似的泥主要在 9.0 cal 以后被扔。ka BP,什么时候海平面的玫瑰慢慢地在 Meltwater 脉搏 1C 以后;舞台 2 在 mid-Holocene sealevel highstand 以后, clinoform 在大陆人架上发展了离开西方广东省,延长 ca。从 Zhujiang 河河口的 400 km。近似 clinoform 变瘦近海,从 ca。在到在 2030 m 水深度附近的不到 12 m 的 510 m 水深度附近的 10 m 厚度。另外,我们也在 Leizhou 半岛的东方发现发达远侧的 clinoform。
High-resolution Chirp profiling and coring reveals an elongated (ca. 400 km) Holocene Zhujiang River (Pearl River)-derived mud area (maximum thickness 〉 20 m) extending from the Zhujiang River Delta, southwest-ward off the Guangdong coast, to the Leizhou Peninsula. Two depo-centers, one proximal and one distal, are identified. On the continental shelf off the west Guangdong Province, the mud is deposited in water depth shallower than 50 m; while to the southeast of the Zhujiang River Estuary, the mud area can extend to the -120 m isobath. A combined analysis with the stratigraphic sequences of other muddy deposits in the West-ern Pacific marginal seas (mainly Changjiang (Yangtze) and Huanghe (Yellow) Rivers derived) indicates that the initiation of the Zhujiang River muddy deposit can be further divided into two stages: Stage 1 is before the mid-Holocene sea-level highstand (ca. 7.0 cal. ka BP), the proximal mud was mostly deposited after 9.0 cal. ka BP, when the sea-level rose slowly after the Meltwater Pulse -1C; Stage 2, after the mid-Holocene sea-level highstand, clinoform developed on the continental shelf off the west Guangdong Province, extending ca. 400 km from the Zhujiang River Estuary. The proximal clinoform thins offshore, from ca. 10 m thickness around 5-10 m water depth to less than 1-2 m around 20-30 m water depth. In addition, we also find a de-veloped distal clinoform in the east of the Leizhou Peninsula.
