珠江口盆地西部生物礁与火山岩的辩证识别
|
摘要
探讨生物礁与火山岩等疑似礁体的辩证差异,厘清珠江口盆地西部浅层地震异常体的地质属性。从琼海24-2异常体所处地理环境出发,结合南海北部生物礁发育的大背景和珠江口盆地生物礁发育的演化规律,重点从生物礁发育所必备的各种地质条件及其地震响应特征进行辩证分析。结果表明琼海24-2异常体所处地理环境不具备生物礁发育的地质条件,地震反射特征具有明显的火山穿刺现象,且属后期破坏型火山活动,因此琼海24-2是受火山活动影响复杂化的异常体,不是生物礁,也不满足火山旁侧发育生物礁的模式,勘探风险较大。
This paper discusses the dialectical differences between reefs and volcano rocks of the suspected reefs,clarifies the geological property of the shallow seismic anomalous body in the west of Pearl River Mouth Basin.Starting with the geographical environment of the Qionghai 24-2anomalous body and combined with the development of the northern South China Sea reef and the evolution rule of the Pearl River Mouth Basin reef,this paper emphatically and dialetically analyses the various geological conditions essential for the reef development and the seismic response characteristics.The result shows that there are no geological conditions for the reef development in the geographical environment of the Qionghai 24-2anomalous body.The seismic reflection characteristics have obvious piercing phenomena of the volcanos,which belong to the later destructive volcano activities.Therefore,Qionghai 24-2anomalous body is neither reef,nor satisfies the model to develop reefs beside volcanos.It is a complicated anomalous body with a great risk for exploration.
