Five principal tmigenous rock types occur within the
sections; sands and sandstones (20%), conglomerati~ siltstones
(BOO! of the total sequ-) and gravely silt (9%), shale and'
mudstones 66%) d carbonaceous shale and shale (5%). From the.
natw and mode of murrence, the coal bearing stmta seems td be
of fluvide origin deposited on the basalt substratum (Jelenc,,
1966; Getmbh, 1'985; Wolela, 1991, 1995). Petrographical and
chemical studies conducted by Babu eb al., 1980, revealed that the
coal in Mush Valley has high moisture (19.3-2 1.34%) and ash
content (52.1-54.2 % in hsh and 22.2% in dry), low carbon
content (1.343.09 in fresh and 38,53 in dry) and low calorific
value (3,82Q-4,020 cdkg in fresh and 4,552 W g in dry).
Cbilga cod depodt (Gondrmr)
The Chilga coal deposit is by f& the best known lignite deposit in
Ethiopia It is situated northwest of Lake Tam (7'1 0'-T15'N and
36O45'-36"55'E); not very fm from the capital of Gondar, and has
' drawn artention since 1 93 0s. A total of 98 sq km was gedogically
mapped by Heeman Wolfgang, Minye Behu and ~~leia in 1988.
The area consists of Trap volcmics and sedimentmy rocks. The
sedimentary sequence lies on a basaltic substratm which is
Oligocene in age. The fluvial-lacustine coal bearing is mainly
composled qf terrigenous clasts of (argillaceous and maceous
maWs), orgamgenic deposits of cod ad mbmgillites. The
thickness of the coal seams mge between 0.5-2.5 m.
Delbi maat deposit (Ulubab~r)
The Inter-Trappean fluvial-hdne coal and oil W e bearing
sediment of Delbi is situated within the geogqhic coordinates 7'
21 '-7" 24'N and 36" 5'-36" 53'E. Delbi is located 390 km southwest
of Addis Abbq and 50 km south of Jimma. The Delbi cod
and shale occurrence is one of the best studied coal deposit in
Ethiopia using bore holes by Water well drilling project, 1983;
Woleh er a]., 1991; Wolela et al., 1995; and others. The a m
