2+] suggests that the precipitation of magnesian
calcite, hydromagnesite, nesquehonite, or sepiolite is almost negligible in the soils under study.
It is suggested that inclusion-rich spar records the former presence of a prolific microbial binder of unknown affinities, which induced precipitation of magnesian
calcite that was later either neomorphosed to inclusion-rich calcite (c.
Kimberlite is a host rock to diamonds, but not a source rock: Kimberlite indicator minerals consist of pyrope and eclogitic garnets, magnesian
ilmenite, chromite, chorine diopside, forsteritic olivine and diamond and the presence of these minerals is used to determine the proximity of diamond-bearing kimberlites.
2) was in the sequence: kieserite granules (1-3 mm) [is greater than] calcined magnesite powder ([is less than] 1 mm) [is greater than] calcined magnesite granules (1-3 mm) [is greater than] magnesian
limestone (65% [is less than] 1.
The area of interest contains chrome rich magnesian
pyrope garnets of mantle origin, one of which is a G-10 garnet indicating a high potential for a diamondiferous kimberlite.
Whereas the continental massifs are old (billions of years, on average), thick, and composed of silica-rich rocks such as granites and andesite, the oceanic crust is young, thin, and composed of silica-poor magnesian
lavas such as basalt.
They are being treated with heavy liquids, by magnetic and paramagnetic separation, and will be studied for the presence of KIM's: pyrope garnet, picroilmenite, chrome spinel, chrome-diopside and magnesian
To the north of the lighthouse is The Leas, a two-and-a-half mile stretch of magnesian
limestone cliffs, wave-cut foreshore and coastal grassland.
2011 Some specific features of interaction of magnesian
clay with calcium hydroxide when new materials are synthesized and a microstructure is formed.
Durham Wildlife Trust has taken over responsibility of Cross Gill grasslands on the Durham coast, which houses nine hectares of rich magnesian
It occurs as the result of low temperature solutions precipitating gold, silver and sulphide minerals in limey, magnesian
and carbonaceous sediments, which have first been made porous by acid solutions emanating from nearly intrusions and fragmentation from fault activity.
Chl is always more magnesian
than Pmp), there appear to be two populations of Chl-Pmp pairs based on the slope of the joins: (1) samples 1,5 and 17 show shallower slopes on the projection (i.

It's made up of three sections of Magnesian
Limestone grassland, cliffs, denes and stacks.
It suggests that carbonate sediments might have undergone early diagenetic stabilization to low magnesian
calcite before dolomitization.
