The document investigates the ocean-continent boundary offshore West Africa, specifically Gabon, and the Gulf of Mexico. It details the application of marine gravity and magnetic data, including both 2D and 3D modeling, to decipher deep crustal structures, identify basement depths, and assess petroleum source rock distribution. By integrating satellite-derived gravity data with high-resolution regional surveys, the analysis provides essential constraints on the structural framework and geophysical lithology necessary for effective geological risk assessment and resource exploration in complex sedimentary basins.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research
