Geology
As quoted from Charles Lyell's Principles of Geology:
Strabo... enters largely, in the Second Book of his Geography, into the opinions of Eratosthenes and other Greeks on one of the most difficult problems in geology, viz., by what causes marine shells came to be plentifully buried in the earth at such great elevations and distances from the sea.
He notices, amongst others, the explanation of Xanthus the Lyclian, who said that the seas had once been more extensive, and that they had afterwards been partially dried up, as in his own time many lakes, rivers, and wells in Asia had failed during a season of drought. Treating this conjecture with merited disregard, Strabo passes on to the hypothesis of Strato, the natural philosopher, who had observed that the quantity of mud brought down by rivers into the Euxine was so great, that its bed must be gradually raised, while the rivers still continued to pour in an undiminished quantity of water. He therefore conceived that, originally, when the Euxine was an inland sea, its level had by this means become so much elevated that it burst its barrier near Byzantium, and formed a communication with the Propontis, and this partial drainage had already, he supposed, converted the left side into marshy ground, and that, at last, the whole would be choked up with soil. So, it was argued, the Mediterranean had once opened a passage for itself by the Columns of Hercules into the Atlantic, and perhaps the abundance of sea-shells in Africa, near the Temple of Jupiter Ammon, might also be the deposit of some former inland sea, which had at length forced a passage and escaped.
But Strabo rejects this theory as insufficient to account for all the phenomena, and he proposes one of his own, the profoundness of which modern geologists are only beginning to appreciate. 'It is not,' he says, 'because the lands covered by seas were originally at different altitudes, that the waters have risen, or subsided, or receded from some parts and inundated others. But the reason is, that the same land is sometimes raised up and sometimes depressed, and the sea also is simultaneously raised and depressed, so that it either overflows or returns into its own place again. We must therefore ascribe the cause to the ground, either to that ground which is under the sea, or to that which becomes flooded by it, but rather to that which lies beneath the sea, for this is more moveable, and, on account of its humidity, can be altered with great celerity. It is proper,' he observes in continuation, 'to derive our explanations from things which are obvious, and in some measure of daily occurrence, such as deluges, earthquakes, volcanic eruptions, and sudden swellings of the land beneath the sea; for the last raise up the sea also, and when the same lands subside again, they occasion the sea to be let down. And it is not merely the small, but the large islands also, and not merely the islands, but the continents, which can be lifted up together with the sea; and both large and small tracts may subside, for habitations and cities, like Bure, Bizona, and many others, have been engulfed by earthquakes.'
In another place, this learned geographer, in alluding to the tradition that Sicily had been separated by a convulsion from Italy, remarks, that at present the land near the sea in those parts was rarely shaken by earthquakes, since there were now open orifices whereby fire and ignited matters and waters escaped; but formerly, when the volcanoes of Etna, the Lipari Islands, Ischia, and others, were closed up, the imprisoned fire and wind might have produced far more vehement movements. The doctrine, therefore, that volcanoes are safety valves, and that the subterranean convulsions are probably most violent when first the volcanic energy shifts itself to a new quarter, is not modern.
The very first written definition/discussion on the fossil formation (mentioning Nummulite quoted from A.M. Celâl Şengör).
One extraordinary thing which I saw at the pyramids must not be omitted. Heaps of stones from the quarries lie in front of the pyramids. Among these are found pieces which in shape and size resemble lentils. Some contain substances like grains half peeled. These, it is said, are the remnants of the workmen's food converted into stone; which is not probable. For at home in our country (Amasia), there is a long hill in a plain, which abounds with pebbles of a porus stone, resembling lentils. The pebbles of the sea-shore and of rivers suggest somewhat of the same difficulty ; some explanation may indeed be found in the motion in flowing waters, but the investigation of the above fact presents more difficulty. I have said elsewhere, that in sight of the pyramids, on the other side in Arabia, and near the stone quarries from which they are built, is a very rocky mountain, called the Trojan mountain; beneath it there are caves, and near the caves and the river a village called Troy, an ancient settlement of the captive Trojans who had accompanied Menelaus and settled there.
The very first written definition/discussion of volcanisim (Effusive eruption) observed at Katakekaumenē (modern Kula, Western Turkey) until Pliny the Younger witnessed to the eruption of Vesuvius on 24 August 79 ADPompeii
…There are no trees here, but only the vineyards where they produce the Katakekaumene wines which are by no means inferior from any of the wines famous for their quality. The soil is covered with ashes, and black in color as if the mountainous and rocky country was made up of fires. Some assume that these ashes were the result of thunderbolts and sub‐ terranean explosions, and do not doubt that the legendary story of Typhon takes place in this region. Ksanthos adds that the king of this region was a man called Arimus. However, it is not reasonable to accept that the whole country was burned down at a time as a result of such an event rather than as a result of a fire bursting from underground whose source has now died out. Three pits are called “Physas” and separated by forty stadia from each other. Above these pits, there are hills formed by the hot masses burst out from the ground as estimated by a logical reasoning. Such type of soil is very convenient for viniculture, just like the Katanasoil which is covered with ashes and where the best wines are still produced abundantly. Some writers concluded by looking at these places that there is a good reason for calling Dionysus by the name (“Phrygenes”)”
