K-T GeoServices, Inc. was formed in October of 1994 from the X-ray diffraction lab of the research division of ARCO Oil and Gas Company. This research division, known as ARCO Exploration and Production Technology (AEPT) was located in Plano Texas (USA). K-T GeoServices bought all of the equipment in the AEPT X-ray diffraction laboratory and opened a laboratory in Richardson Texas in October of 1994. From the start K-T GeoServices has been equipped to perform quality X-ray diffraction analysis. James Talbot began working at the AEPT X-ray diffraction laboratory in 1992 and has been with K-T GeoServices since it opened in 1994. K-T GeoServices moved from Richardson to Argyle Texas in August of 2000.
In June of 2010, K-T GeoServices moved to Gunnison Colorado where it is presently located.

Bulk and Detailed Clay (<4 micron) XRD Analysis
A Bulk and Clay (<4 micron) XRD Analysis involves semi-quantitative (weight percent) determination of all rock-forming and clay/phyllosilicate minerals. Also included is determination of mixed-layer clay types, ordering, and percent expandable interlayers (if any).
Bulk (Whole-rock) Only XRD Analysis
Bulk (whole rock) analysis by XRD involves quantitative determination of rock-forming minerals and total clay minerals. A final data table includes calculation of weight percent mineralogy.
Bulk only analysis is usually used with carbonate rocks or other rocks that have low clay content or when the clay mineralogy is unimportant.
A bulk analysis can be done by itself but it is usually combined with a clay analysis to completely characterize a sample. A Bulk and Clay (<4 micron) XRD Analysis involves semi-quantitative (weight percent) determination of all rock-forming and clay/phyllosilicate minerals. A final data table includes weight percent mineralogy. Also included is determination of mixed-layer clay types, ordering, and percent expandable interlayers (if any).
Clay-size (<4 micron) Only XRD Analysis
Semi-quantitative determination of clays and other minerals in the <4 micron fraction. A final data table includes calculation of weight percent mineralogy, weight percent <4 micron material, and determination of mixed-layer clay types, ordering, and percent expandable interlayers (if any).
A Clay analysis can be done by itself but it is usually combined with a Bulk analysis to completely characterize a sample.
