(PDF) GEOPHYSICAL TECHNIQUES AND THEIR APPLICATIONS IN

Historically, geophysical technique (magnetic) was first used in Sweden in the 17th century for prospecting iron ore (Reedman, 1979). Geophysical techniques gained more acceptability in the early 1923 (Gupter, 1986) because of exploration for crude oil. Relevance of Geophysics across the world is as a result of oil and solid mineral exploration.

Casing correction of slimline density logs for iron ore

Mar 22, 2019 Slimline geophysical logs are frequently used worldwide in iron ore exploration because they provide key data for ore evaluation. Application can be limited by the fact that many formations associated with iron ore deposits are friable, increasing the occurrence of borehole collapse before geophysical logs can be obtained.

Geology, Prospecting and Exploration for Iron Ore Deposits

Apr 09, 2015 The geophysical techniques used in the search for iron ores, as in most geophysical mapping, are based upon the presence of measurable contrasts of physical properties between the ore minerals and the surrounding rocks. The physical properties used principally are magnetism (both permanent and induced) and density.

Apr 14, 2021 The areas with iron ore deposits were expressed in the geophysical results by low resistivity, high chargeability, and moderate to high magnetic anomalies. Integrated interpretation of the obtained results revealed that the ore deposits exist in the form of lenses with variable thickness ranging from few meters to about 30-m thick.

The grouper still notes and samples everything mineralized outside the known zones but the bulk of the logging time is in and around known ore zones. Separators pull out every change in core lithology, mineralogy and structure. Their logs are highly detailed and this type of logging is a must for new logging areas without well defined ore zones.

Exploration geophysics

Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most often used to detect or infer the presence and position of economically

The mining of stratiform ore deposits requires a means of determining the location of stratigraphic boundaries. A variety of geophysical logs may provide the required data but, in the case of banded iron formation hosted iron ore deposits in the Hamersley Ranges of Western Australia, only one geophysical log type (natural gamma) is collected for this purpose.

Application of the gravity method to iron ore exploration

The gravity method was first applied to Fe ore exploration as a tool for detecting nonmagnetic ores, but advantages of this method over other exploration methods have also made it useful under certain geological conditions in the study of magnetic ores and regional structures favorable for the occurrence of Fe ore.

Well logging

Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs).Some types of geophysical well logs can be done
