In approaching the Sierra de Chilicauquen, the granite rock disappears & in its place greenstone rocks appear. — These consists generally of a compact slate coloured bases with slaty structure like (A*) which sometimes contains
acicular crystals of glassy feldspar, at othertimes common feldspar.
— The bases in many places become granular & crystalline then earthy without crystals so that having a slaty structure, which is common to much of these
rocks, it appears like siliceous green altered clay—slate — I found in two places the cleavage running SSE & NNW — Perhaps the most porphyritic varieties were at the
upper parts of ridge; this Sierra runs E & W. — As far as I can see there is nothing to lead me to suppose this mountain has been formed differently from the Cuestas near

Descending in the most direct line, a very steep side there is much of what I call the altered
Slate of which (O) is another specimen — this rock has a distinct cleavage, & coloured bands all parallel — I was surprised a parallel layer, with a gradual passage of the two rocks of greenstone (P) Again altered slate do with many parallel layers of the green
mineral so common at the summit:
Above many 100 feet thick.
There is a great fragmentary of a red color & more or less crystalline.

nor shows there & than other parts. This forms the main
basis of mountain, has entirely lost all cleavage passes into & contains much pale Porph (T) & pale purple Porphyry (V)
Beneath There was also a fine greenish porphyritic greenstone, but at this point the section finishes, for the road followed a winding as descending course, amongst
the hills at base of mountain, generally however it continued Porphyry — At the very basal parts some greenstone & a sort of gneiss, decomposed, without mica. — It is clear all these Porphyry, slates, are the same, which appeared still more so in the undulating & ascending

This descent was at right angle to direction, towards Escarpment.—

I have to remark in the lower part no where have I seen such glassy greenstone as at summit —
I feel no doubt that the appearance of whole above mass of rocks is owing to heat having different action on different layers of sedimentary rocks — (I omitted to state that much of the lower porphyry, consists in the basis alone of harsh texture, like what
I called Limestone in which there have been worked Gold mines) — how else can we account for the layer of greenstone: Is all the Porphyry grewwacke altered, I feel no doubt it is in this case, — Is the upper greenstone flowed
out through N & S — Rent, tilted rocks on each side, hence a vertical cleavage would dip towards the hills: Old puzzle comes into play — Is the gneiss the lowest & most affected rock?

Proceeded up the valley — remarkable agriculture, aquaducts, peach-blossom, orange trees & date-palms.
the rocks we saw were chiefly much altered slates, red Porphyries, in some places with apparent breccia — much very
fine & largely porphyritic greenstone — Also there was a good deal of gneiss without mica which alternated with an imperfect greenstone; some of the high hills, from color porphyry — (There must be a transverse ridge to the E. of the S. de Palmas although I could make but

1 Listed as Canis magellanicus in Mammalia p. 10, plate 5: '[This animal] is mentioned by Molina in his account of the animals of Chile, under the name of Culpeu, which he supposes to be derived from the Indian word "culpem," signifying madness; for this animal, when it sees a man, runs towards him, and standing at the distance of a few yards, looks at him attentively. He adds, although great numbers are killed, they do not leave off this habit. Molina states that he has repeatedly been a witness of this, and I received nearly similar accounts from several of the inhabitants of Chile: yet I must observe, that the people of the farm-house, where my specimen was killed (after it, together with its female, had destroyed nearly two hundred fowls) bitterly complained of its craftiness. From this bold curiosity in the disposition of the Culpeu, Molina thought that it was the same animal as that described by Byron at the Falkland Islands, but we now know that they are different.'

Presumably Darwin refers to one of these reports. The paper was later published as Murray 1826. This line was copied into Darwin's Edinburgh notebook, Barrett et al. 1987, p. 477.

[section continued from previous page]
The slaty greenstone at summit of mountain connected with this dyke Porphyry Dep SW by 12°
This drawing [pp. 66a-67a] represents a mass of bright red jaspery rocks & breccia — conglomerate dipping at ∠ 12˚- 15˚ to [about] SW by S. (The rock is fragmentary in patches more than in planes) This is penetrated in every direction by dykes, zig-zag — strata-shaped or of every sort of grey, slightly porphyric greenstone: the main dyke is from 15 to 20 ft wide, & rises from a pap of similar rock — in the
smaller veins, such sides prove it is crack opened & filled, edge tinged purple, but quite distinct & fine; numerous projections show much melted matter has not
flowed through it — the drawing does not represent nearly all or the intricacy of these dykes; rock not particularly altered: These beds reach 3 or 400 ft high above them is a mass of equal height of rock like the dykes, in every respect, excepting in having few crystals of feldspar — this is a conformable mass to the strata of breccia: the junction of the two rocks is quite gradual in colour & nature: the main dyke
I believe seems to penetrate it, equally
with the Brecia but I could not prove it: till I had noticed these facts I believed it to have been melted mass which had flowed through the cracks; but the above reasons show it to be altered bed. in same degree as Breccia is altered. (Quartz pebbles might be seen in Breccia) at no great distance down the stream I found the Breccia
bed: I believe latter? — On Rt Hand there is a mass of pale purple porphyry, with fine whether dyke or ؟ bed of rock like the dykesreposing on conformable
semi = cryst. of Feldspar, which is similarly is covered by the altered rock —
Perhaps In this the Breccia structure could only in one place be distinguished. Perhaps this is protruded mass of melted inferior Brecia, breaking through the semi-porphyritic brecia — as the melted plates have cut through both breccia & altered slates. (We must recollect the vein of Brecia yesterday). — I see no way of distinguishing greenstone produced in situ & ones that have flowed
perhaps this may hold good to Porphyries. — (it is likely, that some of the beds of greenstone have been dykes): — The Brecia being traversed by greenstone as well as Gneiss interesting: — (a mass of Breccias & Slates to a thickness of at least 5000 ft have been baked & altered.

Snow almost down to house. — Most magnificently splendid the view of the mountains: I see that one of the most isolated islands is composed of Breccia which dips to SW, the usual method (will apply to origin of Basins) which helps to show that the greater part of this
space (inclining to seaward) perhaps 10 miles across has been cut by the sea. Crossed the Sierra Talguen, saw a mass of beds dipping at about ∠ of 40˚ to SW. — this great dip shows that the upheaval has not always been so regular. This ridge seems

place rather toward this hill. — At the foot there are some globular concretionary decomposing mass of iron greenstone (Nr5) which I suppose is directly connected with the Porphyry — on the West side there is
some of the pale purple porphyry. — the rock which so many reasons lead me to suppose has been an altered Brecccia in site I imagine from a crack has issued a mass of greenstone through which a grewwacke — which

me that these hills & places have all been formed by water. I was pleased to find on the top of St Lucia & St Chrystophal, a mass of Breccia (& at St Lucia, a variety of rock which is not found on summit) united
