PHOTOGEOLOGYSEISMIC METHODSAMPLE EXTRACTIONSAMPLE HANDLINGASSAYSWHERE TO LOOK FOR GOLD ORESPhotogeology is a very important of gold deposit exploration. It gives complete information of high altitude photography and satellite photography. Images are recorded either on films or by recording the image digitally. Films used include black white, true color, and Infra red. In color photos, the red areas indicate live vegetation. This makes them useful for locating outcrops in highly vegetated areas.Also least affected by fog, and is effective in cloudy environment. It is also good foRead More
