MAGNETIC METHOD. The magnetic method exploits small variations in magnetic mineralogy (magnetic iron and iron-titanium oxide minerals, including magnetite, titanomagnetite, titanomaghemite, and titanohematite, and some iron sulfide minerals, including pyrrhotite and greigite) among rocks. Measurements are made using fluxgate, …

ABSTRACT Electromagnetic signals from distant radio transmitters in the frequency range 15–250 kHz were measured to model an electrical resistivity structure beneath 7 profiles in the vicinity of the Karinu limestone quarry in Estonia with the aim to map the extent of the economically exploitable limestone. The resistivity models from a …

Jubaila Limestone is the oldest rock encountered in the project area, which is of early Kimmeridgian age (157 to 152 Ma). It is composed of 118-m (in the type section) partially dolomitized aphanitic limestone in the lower 85-m depth and calcarenitic limestone in the upper 33-m depth (Powers 1966).The Jubaila Formation can be …

The 300-foot Hillside Landfill was established during the 1970s at the site of a previous limestone/dolomite quarry. Shaw and Raimonde Drilling are core drilling and sampling the bedrock at 11 points surrounding the quarry landfill, and continuous cores are being collected to 200 feet in depth in order to help Shaw Environmental better ...

Qurn Formation is composed of five units; the first unit (at the base) consists of massive crystalline limestone inter-bedded with argillaceous limestone as shown in the composite geological section (Fig. 3). The second unit includes argillaceous limestone, marl and shale. The third unit of Qurn Formation is made up mainly of marl and shale.

A nearby active limestone quarry may also be affecting ground stability. This paper shows how a near-surface geophysical survey could characterize the site, unusually after the initial housing construction had already been undertaken. ... Geophysical surveys included seismic refraction (acquired between phases of quarry blasting), electrical ...

ABSTRACT After conducting a successful GPR pilot study in a tectonically complex area of the Karst Thrust Edge, a follow-up study was carried out. In the pilot study, the geometry and spatial extent of the Socerb thrust-fault, which separates limestone above from flysch below, were investigated using a 50 MHz antenna in the Črnotiče quarry. After one part …

This paper reports on AVA analysis carried out on CMP data acquired with 500 MHz antennae over Carboniferous Limestone with horizontal bedding plane fractures in Yorkshire, United Kingdom. Using the transverse electric (TE) polarization mode, data were collected at a sampling interval of 0.05 ns for offsets at 0.04 m steps from …

Quarter-wavelength spatial sampling is a minimum requirement for full-resolution GPR recording. An intensely fractured limestone quarry serves as a test site for a 100-MHz 3D GPR survey with 0.1 m × 0.2 m trace spacing. This example clearly defines the geometry of fractures in four different orientations, including vertical dips to a depth of ...

Abstract. Various geophysical methods are discussed in relation to their possible value in locating limestone reefs, with special emphasis on the gravity meter and seismograph. The effects of possible velocity variations through reefs on reflections from below a reef body are examined. Relationships between the shallow and deep horizons ...
