In Narukot at the one kno\vn occurrence of rocks of the gondite series 
the interbanded rocks are considerably different to those of the Central 
Provinces and Jhabua. The following is a list : — 
List of rocks inierhanded ivith the rocks of the yondite series in Ndruknt. 
Quartz-rock. 
Red quartzite 
Pyroxeuic quartzite. 
Quartzite containing manganese-ores. 
Manganiferous micaceous schists. 
Whilst intimately associated \vith these are rocks composed of the fol- 
lowing minerals : — Quartz, garnet, pyroxene, epidote, hornblende, pla- 
gioclase, microcline, biotite, wollastonite, sphene, apatite, calcite, tourma- 
line, with in one case, chalcopyrite. The rocks composed of these minerals 
take the form of banded gneisses. 
Amongst the rocks given above as occurring interbanded with the 
rocks of the gondite series are in all three areas ' manganiferous micaceous 
schists'. These rocks are often of very complex composition owing to 
the great variety of minerals they contain. The following is a more de- 
tailed hst of these rocks : — 
List of the manganiferous micaceous schists found associated with the 
rocks of the gondite series. 
In the Cfutral Provinces : — Only known to occur to any extent at one locahty 
Kacharwahi. These have not yet been examined. 
In Jhabua : — Found at KajUdongri. Apart from the rocks containing the blue 
amphibole, winchite. and of which a list will be given below, the 
following rocks can be included in this group, talc sometimes taking 
the place of the mica ; — 
Mica(yellow)-fock. 
Apatite-talc( ? )-felspar-quartz-rock. 
jVIiea(crimson)-amphibole-apatite-talc-rock. 
Apatite-mica(orange)-blanfordite-quartzite. 
In Narukot : — Found at Jothvad. The manganiferous micaceous schists are such 
as, from their outward physical aspect, one would designate ' biotitic 
sandstones' in the field. The following is a list : — 
Schistose banded rock containing the following minerals in one 
band : — apatite, microcline. plagioclase. quartz, manganese-ore 
(probablj' original), mica (showing pleochroism in pink, green, 
and orange), and a little of a blue pjToxene ; with a second band 
formed of quartz, apatite, manganese-ore, and pjToxene, 
, pleochroic in pink and bluish green. 
Schistose rock composed of apatite, mica, microcline, quartz, 
manganese-ore. pjToxene (pink and green pleochroism). and 
an amphibole having the pleochroism of winchite. 
Sc'iistose rock, included in granite, containing quartz, microcline, 
apatite, spessartite, mica (orange brown), hematite plates, and 
a black ore.
