广东沿海地区现代地壳垂直运动研究

对３０多年来１万多ｋｍ精密水准复测数百个重合点资料进行了综合研究，结果表明，广东沿海岸段的地壳平均以－０．５ｍｍ／ａ幅度沉降，表现出粤西抬升，粤东沉降，珠江三角洲大面积下沉的格局。粤西岸段平均以＋０．６ｍｍ／ａ速率上升，粤东沿海岸段平均以－０．７ｍｍ／ａ速率下降；珠江三角洲以－１．８ｍｍ／ａ速率下沉，桂东南岸段则以＋３．４ｍｍ／ａ的速上升。

Geochronology, geochemistry and tectonic implications of Xiongshan diabasic dike swarm, northern Fujian

Sm/Nd isotopic age determination showed that Xiongshan dike swarm was at 585.7 Ma ± 30 Ma. The trace element geochemistry and Sr/Nd/Pb isotope gemhemistry studies indicate that the dike swarm was products of back-arc basin spreading ridge and the magma originated from the depleted mantle region which was metasomatized by LILE-rich liquids/melts derived from subduction slab.

闽西北常口—南舟断裂带与萤石成矿关系

福建省区域地质调查队三分队在元坑幅及埔上幅１：５万区调中分别发现了将乐常口大型萤石矿和顺昌南舟萤石矿。两个矿床均位于常口－南舟北东向断裂带中，受其次级张性断裂直接控制，矿床成因类似。     

福建黄地金-多金属矿床地质特征

黄地金-多金属矿床严格受黄地逆冲推覆断层控制,矿脉(体)赋存于由推覆体构造带上下盘岩石所形成的碎裂岩化、糜棱岩化带中,并且金、铅、锌在空间上具有分段富集的特点.矿石为动力变质多金属硫化物蚀变岩型,主要有自形-半自形、他形粒状,包含、碎裂等结构,块状、浸染状、角砾状等构造.金属矿物主要有黄铁矿、磁黄铁矿、方铅矿、闪锌矿以及银金矿和自然金,非金属矿物主要为石英和绢云母.自然金主要产于黄铁矿的晶洞中,少部分包裹于非金属矿物中.成矿作用可分为岩浆接触交代期、气-水热液矿化期和氧化期,其中气-水热液矿化期的早期石英-硫化物阶段为主成矿阶段,成矿物质主要来源于动力变质作用所形成的深部矿化热液,为沿推覆构造充填交代所形成.     

Coastline configuration and geomorphologic development mode of arc-shaped coast in South China

1IntroductionArc-shaped bays are quite common on exposed sediment coast in South China, where the crenulate-bay beaches occur with the presence of two consecutive headlands and a predominant wave approach oblique to the alignment of the upcoast and downcoast headlands (Yasso, 1965). Oblique persistent swell striking a shoreline transports sediment alongshore and sculptures a coast into arc-shaped beaches. The shoreline of beach appearance mainly consists of straight segment and shadow segment…     

The development of talus slopes around Lord Howe island and implications for the history of island planation

Lord Howe Island is a small eroded remnant of a Late Miocene shield volcano. A fringing coral reef dissipates wave energy along a portion of the shoreline, but the remainder of the coast is rugged with spectacular high basaltic sea cliffs. This paper investigates the evolution of talus slopes that occur beneath the loftiest cliffs, and places this analysis within the context of a longer history of island planation that has resulted in a wide truncated shelf around the island. During the Last Glacial, when the sea level was lower than at present, talus slopes accumulated around the extent of the island's cliffed coast because material eroded from cliffs by subaerial processes could not be removed by marine processes. The survival of these slopes during the Holocene has depended on a balance achieved between rates of subaerial and marine erosion. This balance is fundamentally influenced by cliff height, as cliffs higher than 200 m are plunging or veneered by talus slopes, whereas lower cliffs have erosional shore platforms. On comparison with published erosion rates from inland basalt scarps it appears that marine processes may account for over 90 per cent of the total cliff retreat that has occurred at Lord Howe Island, yet contemporary coastal morphology attests to the significance of subaerial processes in recent times. It is likely that marine cliffing was very rapid soon after volcanism ceased, but rates of erosion decreased through time as wave energy became increasingly attenuated across a widening planation surface, and as increasing cliff heights yielded greater quantities of talus that provided protection from rapid marine erosion.
