Assam Mineral Development Corp. Ltd., Umranghsu Limestone Area 4.6 Regional geology & local geology:

Regional geology:-

The thick pile of Eocene sediments starting from Basal sandstone Formation (Equivalent to Cherra Sandstone Formation) to Kopili Formation of the Jaintia Group is exposed in the Garampani-Umrangshu area over the Precambrian basement. Towards south-east, the Jaintia are conformably overlain by the litho units of the Barali Group.

The Basal Sandstone Formation occupies its position just above the Pre-cambrian basement and exposed intermittently from near Panimur to Kopili – Kharkar confluence covering a distance of about 40 km. The litho units of formation are well exposed near Eili Falls and Panimur-Lanka areas.

The limestone deposit of the area belongs to Sylhet-Limestone Formation of Jaintia Group. It occupies a large tract and exposed intermittently in NW-SW direction. The best section of this formation is exposed along the Amrang valley of Juiphar block. However, the major portion of the area covered by the alternating sequence of shale and sandstone of Kopili Formation. The Bottom most position of the Kopili formation is calcareous, the middle portion is argillaceous in nature. The litho units of the formation are found in a continuous sequence at places. The contact between the formation are either gradational or sharp.

The general stratigraphic sequence of the area is as given below:

Group Formation Lithological units

Jaintia

(Eocene) Kopili Shale & Sandstone Alternation of splintery shale and fine to medium grained brownish sandstone, with occasional bands of calcareous shale.

Sylhet Limestone Formation

Thick limestone, fossiliferous, hard , well bedded with occasional partings and bands of shale.

Granite and various gneissic rocks

The traps and Pre-Cambrian has very few exposures. Highly weathered traps exposed along the Lumdingnala and the pre-cambrians are explored along the Khandong ridge and at the dam site of the Kopili Hydel Project, west of the lime stone deposit.

Kopili shale and sandstones normally cap the limestone. The main exposure seen in The Umrongshu valley, which is a faulted block entirely, formed of Kopili shale and sandstone. Other good outcrops are seen at many places along Umrongshu –Lanka road.

The limestone deposit lies along the eastern side of the Umrongshu – Lanka road at a distance of about 5 km. from Umrongshu township. It is exposed over an area of 11 sq.km. The present prospect forms the western flank of the AMDC block of the deposit. The limestone is exposed along the bed of the deep ravine curved out by the Amrang nala. The Amrang Nala flowing on NNE-SSE course within the prospect, has moderate to steep gradient.

The block consists of two distinct limestone beds intervened by a thin but consistent shale band of approximately 6 – 8 m thick. The top and bottom bands are about 30 – 80 m thickness. The Kopili shale and sandstone immediately overlies limestone sequence occupying the high ground along the ridges. A thin mantle of top soil normally covered the Kopili formation. The bottom band limestone is underlain by Quartzite sandstone.

Assam Mineral Development Corp. Ltd., Umranghsu Limestone Area Kopili Sandstone & Shale:

The Kopili formation forms the Top most unit of the Jaintia Group and is composed of alternation of gray to brown splintery shale and yellowish brown sandstone . Thin bands of calcareous shale and impure limestone are also seen at places. The sandstone is medium to fine grained well sorted, whitish to brown in colour. It is soft and sometime friable. The shale is dark gray to brownish in colour and splintery in nature.

Sylhet Limestone: (Top Band Limestone);

The top limestone band shows an average thickness of 28.00 m. Top 3.0 to 5.0 m is ferruginous and red in colour. The colour gradually changes from dirty grey to fresh grey orientation of fossils in a definite direction and low to heavy concentration of fossils at certain horizons is the peculiar characteristics of this ferrugineous limestone. Calcite crystallization along the fractured planes are common. Towards the bottom of the colour of the limestone varies from light grey to buff and then gradually to grey. Fossil mainly nummulites) contents also varies a different vertical sections. CaO content seems to increase towards bottom of this band. Chemical analysis of this band shows high percentage of R2O3 and low percentage of CaO.

Intermediate Shale :

The top band and bottom band limestone are separated by a thin but persistent shale band, thickness of which varies from 5.0 to 6.0 m. The shale is dark gray in color with occasional thin shally limestone band.

Bottom Band Limestone:

In general immediately below the intermediate shale band the bottom band limestone is encountered in almost all the boreholes of the area. The contact is observed to be gradational one the average thickness of this band is 48 meters. Limestone of this band is grey to dark grey in colour and less fossiliferous. In contrast to the Top band
