MANGANESE DEPOSITS OF INDIA : GEOLOGY, [ParT II : 
containing manganese before they reached their present position. The 
following is a list- of these intrusives : — 
Li^t of rocks intrusive in the. rocks of the gondite series. 
In the Central Provinces : — 
Pegmatite (Ramdongri). 
Spessartite-pegiuatite (Bichua, Ghoti, and Satak). 
Pyroxene-{brown)-pegmatite (Sitapathui-). 
Quartz-felspar-rock with a brown mineral (Thirori). 
Felspar-rock with spessartite (Hatora). 
Microcline-rock with spessartite and quartz (Beldongri). 
Microcline-rock with brown pyroxene and bronze-coloured mica (Kosumbah). 
Albite-rock with braunite, blanfordite, juddite, and sometimes quartz 
(Kacharwahi). 
Blanfordite-granite (Ramdongri). 
In Jhabua : — 
Quartz-oligoclase-albite-carpholite(?)-rock (Kajlidongri). 
It is uncertain whether this rock is to be classified with the intrusives or 
with the mineral veins ; it is here put in the former class on account 
of the presence of felspar, although felspar is also sometimes found in 
mineral veins. 
In Nariikot : — 
Granite vein containing red garnet and a little pyroxene with pink and green 
pleochroism. 
Granite vein with blanfordite, greenovite, and garnet. 
Quartz-felspar(microcline and oligoclase)-rock. 
Porphyritic biotite-granite. 
In addition to the rocks enumerated above, which are found in the 
masses of the gondite series as veins or irregular patches, and are to be re- 
garded a? the products of the intrusion and subsequent solidification of 
igneous or aqueo-igneous magmas, there is another set of vein-rocks 
that are probably to be regarded as true mineral veins deposited 
by mineralized waters percolating along cracks or fissures. The following 
is a list of such veins : — 
List of the mineral veins found traversing the rocJcs '»/ f^:e gondite series. 
In the Central Provinces : — 
Quartz. 
Quartz with spessartite{?) (Hichua) 
Quartz with magnetite (Sltapathur). 
Tourmaline-quartz-rock(?) (Koilegaon). 
Pyrite in (|uartz{V) (Kodegiion). 
Opal (Kodegaon and Kandri). 
Chalcedony (Kandri). 
Hematite (Mansar Fxtension). 
In Jhabua (at Kajlidongri) : — 
Hollandite and quartz. 
Hematite and quai'tz. 
Barytes and ((uartz, with an arsenate. 
Quartz with angular inclusions of psilo.nel in \ 
In Narukot : —
