APPENDIX 2.

REPORT FROM R. BROUGH SMYTH, ESQUIRE,

SECRETARY FOR MINES OF VICTORIA,

ON THE GEOLOGICAL SPECIMENS COLLECTED ON THE EXPEDITION.

COLUMN 1: POSITION OF LOCALITY WHERE THE SPECIMEN WAS COLLECTED.

COLUMN 2: REMARKS BY MR. JOHN FORREST ON THE SPECIMENS FORWARDED.

COLUMN 3: MR. R. BROUGH SMYTH'S REPORT ON SPECIMENS.

Lat.i.tude 26 degrees South, Longitude 117 degrees 20 minutes East : Taken from Mount Hale on the Murchison River. This formation extends to longitude 120 degrees East, and is very magnetic, also very heavy. There must be a great deal of iron in it. The hills are very high, and the echo very remarkable. I have seen the same kinds of hills in lat.i.tude 29 degrees, longitude 120 degrees. Bare granite rocks sometimes in the vicinity, though not attached. (May 4th.) : Two small specimens of Micaceous Iron-ore with brown Haemat.i.te. Impossible to state the age.

Similar ore occurs in Victoria, in Elvans in Porphyry, but it also occurs in Tertiary rocks.

Lat.i.tude 26 degrees 17 minutes South, Longitude 119 degrees 54 minutes East : The water shed of the Murchison, after crossing which we entered the Triodia desert. Found oozing out of rock in the water-shed of the Murchison. : Brown Haemat.i.te, decomposing to yellow. (Tertiary.) Bituminous material. Mr. Cosmo Newbery reports that it is probably the result of the decomposition of the excrement of bats. It contains fragments of the wing cases of insects, and gives reactions similar to the bituminous mineral or substance found in Victoria.

Lat.i.tude 25 degrees 14 minutes South, Longitude 121 degrees East : Peaks rising out of sandy Triodia desert. (May 29th.) : 5, Quartz; 6, Chalcedony; 7, Quartz; 8, Silky Shale (Silurian); 9, very Micaceous Schist (Silurian).

Lat.i.tude 25 degrees 40 minutes South, Longitude 120 degrees 35 minutes East : Found in the Frere Ranges. : 10, Ferruginous rock (Tertiary); 11, portion of a seam or joint of a rock; 12, very fine soft purple slightly micaceous rock (Silurian); 13, white micaceous slaty sandstone (Silurian).

Lat.i.tude 25 degrees 39 minutes South, Longitude 120 degrees 40 minutes East : This rock was broken off the face of the side of a bank of brook.

It is rather soft, and would split; it is all in layers. I cut my initials in it with a chisel. : Purple brown slate (Silurian).

Lat.i.tude 25 degrees 40 minutes South, Longitude 122 degrees 20 minutes East, Mount Moore : Many ranges and some gra.s.sy country running from longitude 122 to longitude 124 degrees, generally composed of this description of rock. : 15, Rough quartzite (conglomeritic) Tertiary; 16, rough quartzite with white band, brown and purple (Tertiary).

Lat.i.tude 25 degrees 32 minutes South, Longitude 124 degrees 17 minutes East : Taken from rough range rising out of gently undulating desert.

(July 5th.) : White flinty rock; consists in the main of Silica, with Magnesia and Alumina; it also contains water and traces of the Alkalies.

It is probably derived from the decomposition of granite. The "rough ranges" are perhaps granitic.

Lat.i.tude 26 degrees 6 minutes South, Longitude 124 degrees 46 minutes East : From a low table hill (Alexander Spring). : Translucent greenish quartz. Impossible to state the probable age.

Lat.i.tude 26 degrees 2 minutes South, Longitude 125 degrees 27 minutes East : This sandstone is the usual rock found in all the country from longitude 122 degrees to 126 degrees 30 minutes. In it are receptacles for water, and all the rising ground is composed of it. Very often one side of the rise forms a cliff. Where this is taken from there is a long line of cliffs with many creeks running from them, and low cliff-hills all about. : Light red sandstone (desert sandstone, Tertiary).

Lat.i.tude 26 degrees South, Longitude 126 degrees 30 minutes East : From the farthest ranges westward from telegraph line; good gra.s.sy country in flats. The dark piece from a salt gully. (August 8th.) : 20, Silico felspathic rock impregnated with Micaceous iron (probably from a d.y.k.e); 21, 22, green schist (Silurian).

Lat.i.tude 26 degrees 12 minutes South, Longitude 128 degrees East : In the Cavanagh Ranges. Many ranges. (August 17th.) : Greenstone (Diabase ?).

Lat.i.tude 26 degrees 18 minutes South, Longitude 129 degrees 9 minutes East : Tomkinson Ranges. Many ranges running East and West, and gra.s.sy flats between them. (August 26th.) Mount Jane. : Aphanite.
