Goniometer - Ezy Logger
Goniometer - Ezy Logger
A quick reference hand-held guide for core logging
“I just completed logging 520metres of HQ-3 core with an Ezy-Logger™. I'll never go back to using a protractor again; it's a great device.”
Dr Anthony (Tony) Meyers
Principal and Senior Rock Mechanics Engineer, Rocktest Consulting
The Ezy-Logger™ has recently been improved!
Due to increasing demand, the Ezy-Logger™ now comes in a more specific range of sizes to give the user greater control.
Also every Ezy-Logger™is now completely laminated to minimise wearing of the printed surfaces.
NTW and PQ Sizes now available!
Cost Benefits:
•A quick and easy method of measuring alpha angles, beta angles and lineations.
•Initial cost of the instrument is relatively cheap.
Technical Benefits:
•The clever design incorporating impact resistant plastic and reinforced protective rims makes for a strong shock resistant product that will give excellent service.
•It should give confidence to any competant user in the basic measurement of structural trends and estimations while logging core samples of a variety of sizes and types.
Servicabilty:
•The Ezy-logger only requires a quick wipe with a damp cloth. Keep clear of heat and organic solvents.
Accuracy:
•The Ezy-Logger should be used as a quick reference guide only and is not designed to be used as a calibrated instrument.
The proprietary, lightweight and robust design of the Ezy-Logger™ allows Geologists and Field Technicians to quickly and easily make structural linear, Alpha and Beta measurements for most core samples and core sizes. The compact size of the product makes it easy to transport and visual readings are easy to observe.
Beta Angles:
The Ezy-Logger™ has two end protractors that are used to determine the Beta angle of a structure. Firstly position the 0° mark over the core orientation line of the core sample. Then read the degree position of the nose of the elliptical structure by rotating clockwise from the core orientation (bottom of hole) line.
Alpha Angles:
The Ezy-Logger™ has two side Alpha protractors (blue & red) that allow for easy visual measurement of the Alpha angle for a variety of rock colours. This is achieved by simply sliding the Ezy-Logger™ up or down the core sample while holding it relative to the Beta angle (nose of the ellipse) and selecting the line of best fit on the side of the Ezy-Logger™ that matches the structure being measured.
Lineations:
Lineations can be measured on open fractures by rotating the Ezy-Logger™ on the core sample, so that the 0° position on the end protractor being used is over the nose of the ellipse for the open fracture being measured and then reading off the degree at which the lineations strike the protractor or exit the core sample.
Linear Measurement:
The Ezy-Logger™ can even provide limited linear measurements from one structure to the next of 0 to 95mm (0 to 3 inches) in length minimizing the need for a set of calipers while handling fragile core samples.
Accuracy:
The simple and cost effective design allows the measurement of a range of core sizes to within 5° or better when used correctly. The Ezy-Logger™ is a quick reference guide only and is not designed to be used as a calibrated instrument and should give confidence to any competent user in the basic measurement of structural trends and estimations while logging core samples of a variety of sizes and types.
Core Sizes:
Due to popular demand, the Ezy-Logger™ is now available in eleven sizes with some variants covering more than one core size.
