Diamicton, a glacial geology
term, refers to unsorted or poorly sorted deposits that are massive to crudely stratified and consist of a poorly sorted matrix with large clasts (< 2 mm) dispersed throughout.
The discoveries of these economically important materials resulted directly or indirectly from the mapping, yielding a benefit-to-cost ratio of $50 to $1, as reported in "Mapping the Glacial Geology
of the Central Great Lakes Region in Three Dimensions -- A Model for State-Federal Cooperation" (USGS report number 99-349, published April 2000).
This winter, glacial geology
studies are being undertaken on 33 CARATS & EXTENSION & results to date are encouraging.
In the front matter is a listing of entries according to the following themes: continents and continental processes, crustal and surface features, earth history and stratigraphy, eruptions, geomorphology, glacial geology
, mountains and mountain ranges, oceanic crust, paleontology and the fossil record, and volcanology and volcanic processes.
Topics addressed by the various papers include origin of the term Quaternary, several biographies, the history of ideas in regional geomorphology and glacial geology
, Australian geomorphology, peneplains in China, as well as Japanese Quaternary history.
Substantial contributions to the understanding of the glacial geology
of Michigan and the formation of the Great Lakes were made during this initial period.
Forsyth's research focused on Pleistocene geology and glacial geology
They cover extending geographical and temporal applications, glacial geology
, active tectonics in Asia, and landscape evolution.

While the glacial geology
in the area is complex, and locating the kimberlite sources of the diamond indicator minerals is proving difficult, the company is confident that it is just a question of time until the source rocks of the angular (near source) indicator minerals containing diamond inclusion compositions are found.
As a general point, with the notable exception of Logan (O-1847), reports on glacial geology
in Canada showed little appreciation of the dynamical behaviour of glaciers, until Bell's (O-1890) startlingly apposite analogy of erosional microforms on granite at Killarney, Ontario, comparing them to ".
The program was designed to test an extensive area of prospective terrain on the Superior Craton by careful consideration of the sampling medium in relation to the regional glacial geology
