the above section, a gap of probably about thirty-five feet intervening. The con- 
s omerate is traceable on the surface for a mile and a-half. A baud of porphyry, 
Pi’obably intrusive, although it follows the line of strike of the sedimentary beds, is 
®een in contact with the conglomerate in the Little Star River a few hundred yards 
above the ford. 
A ga]) of about thirty feet is supposed to separate the last-mentioned con- 
. °®6rate from tlie next higher bed, viz., a coarsely crystalline limestone, about one foot 
thickness, seen in Horse Creek, and showing on its weathered surface sections of 
eJLs {Orthis, &c.), Encrinites, and Corals. A microscopic examination of the limestone 
Matrix in which the larger fossils pro preserved proved it to bo a mass of foraminifera. 
10 forms of the larger shells are perfect, but their substance has been entirely replaced 
J calcspar. Above this limestone lie about twenty feet of thin-bedded calcareous 
^ndstones and shales, dipping to "W. at 30°, aud containing Orthis, Chonetes, and 
steropods, together with Lepidodendron australe, McCoy. To these succeed twenty 
0 of shales and hard dark-blue sandstone, dipping to the south-east; also seen in 
01'se Creek, south of the Station Paddock. 
Next in ascending order, after a gap of about twenty feet, is a coarse con- 
of coarse pebbles, dipping at 60° to N.W., fifteen feet in thickness, seen 
'0 Little Star River at the mouth of Horse Creek. Above this are about twenty 
tl ^ S^ooo shales and fine hard calcareous sandstones, seen in the Little River at 
^0 ford on the Coppermine road. 
^ As no other area in the Star Beds has as yet been mapped in the like detail, the 
wi above described are thrown into tabular form for convenience in future 
“^tnparisons.
