Geophysical investigations in the Bi'r Idimah-Wadi Wassat area, Saudi Arabia, Part Two

Introduction

Geophysical studies were continued in the Bi'r Idimah-Wadi Wassat area during February 1965. Detailed electromagnetic measurements were made along selected traverses over the northern part of the gossan to supplement earlier dip-angle data; and reconnaissance surveys were made over the central and southern parts of the gossan. Gossan is exposed near the crests of prominent hills and is marked by a zone of alteration in the lowland. The geophysical exploratory work was done mostly in the lowland to determine the continuity of the gossan and to delineate associated deposits of massive sulphides.
