Abstract

Described is a method for detecting trace metal anomalies in soil. Soil samples are collected from an area of interest. The soil samples are prepared such that particle size and moisture content of each soil sample is normalized. An extraction solution having an amount of a carboxylic acid, an amount of a chelating agent, and an amount of a strong base is prepared. Using the extraction solution, a soil extract is obtained from each soil sample. Using a spectral instrument, a spectral analysis of each soil extract is performed to detect a chemical element. Based on the spectral analysis, presence of a hydrocarbon microseepage in the area of interest is determined.

A method, comprising:

collecting a plurality of soil samples from an area of interest;
preparing the plurality of soil samples such that particle size and moisture content of each soil sample of the plurality of soil samples is normalized;
preparing an extraction solution comprising an amount of a carboxylic acid, an amount of a chelating agent, and an amount of a strong base;
