The variety of volcanic deposits and intrusions in the Temagami Greenstone Belt indicates that magmatic activity played a significant part in its formation.
32.
These volcanic deposits get mixed up with the sediment from the continent ( now in the form of a back arc basin ).
33.
Volcanic deposits in the Northern Cordilleran Volcanic Province include lava flows, welded and unwelded pyroclastic deposits, hydroclastic deposits and other ice-contact volcanic deposits.
34.
The principal uranium mineral in volcanic deposits is pitchblende, which is usually associated with molybdenite and minor amounts of lead, tin and tungsten mineralization.
35.
People of the villages at the heart of the Cappadocia Region carved out houses, churches and monasteries from the soft rocks of volcanic deposits.
36.
It is thought that its rocks are explosive volcanic deposits, though other possibilities exist, including impact deposits or sediment borne by wind or water.
37.
The well drained soil of this area is composition of gravel, loam and sand with volcanic deposits and marine sediments from the Franciscan Assemblage.
38.
Mordenite is one of the most abundant zeolites in altered volcanic deposits; it is found in volcanic rock such as rhyolite, andesite, and basalt.
39.
The worldwide association of diatomite deposits and volcanic deposits suggests that the availability of silica from volcanic ash may be necessary for thick diatomite deposits.
40.
In more favourable terrain where the volcanic deposits were quickly removed, some plants like " Alnus fruticosa " did survive and quickly resettled the terrain.
