In the argillite
at its highest bulk density, the aeration limit falls below [[Theta].
Christian White is known for his argillite
Results and discussion on the geochemistry of the Estonian graptolite argillite
Surface mapping and prospecting on the Dewdney Trail Property have identified areas with anomalous gold mineralization along a 13 kilometre trend of quartz-sericite-carbonate altered quartzite and interbedded argillites
The sedimentary rocks from the Lontova Formation (Lower Cambrian) up to the Lasnamagi Stage (Middle Ordovician) are represented by clay-, silt-, and sand-stones, argillites
, and dolo-and limestones, outcropping at the steep escarpment of the klint and on the slopes of the Voka Klint Bay (Fig.
Self-ignition of Dictyonema argillite
in Maardu mining waste dumps // Problems of contemporary ecology: Sustainable development and natural lifestyle / T.
Even quite closely spaced locations in the same facies can contain chemically quite different argillite
According to this scheme applied for water conversion products of kukersite, Dictyonema argillite
, pinewood and reed it was found that biomass-derived liquids differ from shale oils by significantly higher contents of water-soluble and acetone-soluble oxygen compounds, the group of the most valuable benzene fraction (the only fraction containing hydrocarbons) being similar.
Estonian oil shale kukersite (locality Kivioli, Estonia) and Estonian dictyonema argillite
(locality Maardu, Estonia) were studied.
This highest value comes from a 3 ft chip sample within a structure within fractured upper-plate argillite
and is duplicated by Miranda's own sampling.
There are two oil shale types in Estonia--Dictyonema argillite
(claystone) and kukersite.
Gold bearing intersections have been included in skarn, marble, diorite and granodiorite, quartz veins, limestone, argillite
, and andesite all containing traces of pyrite.
