Abstract

We examined the elemental distribution originating from the macro- and micro mineral structure of the core samples by two Laser-Induced Plasma Spectrometer (a time-integrated-- LIBS, and a time-resolved one-TRELIBS). We used randomized distribution of the measuring points on cut core samples and on pulverized homogenized ones. For plasma production were used low pulse energy (10 mJ) Q-switched Nd:YAG lasers. The probability frequency of the elements in the core sample was investigated with the help of distribution profiles. The principals of the quantitative evaluation and the calibration technology are also described.
