Sedimentary Rocks Quotes

What are men to rocks and mountains?

The Bad Lands grade all the way from those that are almost rolling in character to those that are so fantastically broken in form and so bizarre in color as to seem hardly properly to belong to this earth.

Thus it cannot be denied that the masses which today form our highest mountains were originally in a liquid state; for a long time they were covered by waters which did not sustain any life.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.

I happen to hold a bachelor of science degree in geology... And my greatest contribution to the field of science is that I never entered it.

The older the layers, the more each of them is uniform over a great extent; the newer the layers, the more they are limited and subject to variation within small distances.

England is not a country of granite and marble, but of chalk, marl, and clay.

Butterflies doing strange things in very beautiful ways were in my mind when I sat down, but by the time my pen was uncapped my thoughts had shifted to rocks.

[Geology] opens up such wide intellectual vistas and supplies a more perfectly unified and more comprehensive conception of nature than any other science.

We choose to believe that the granite is alive. If life is movement, then rock - with its atoms flying around like stars in cosmos - is alive.

When we opened our eyes, we saw bedrock exposed in the walls of the crater.

A stone is ingrained with geological and historical memories.

The trip I made to Angola to study the prehistoric contents of the gravel beds as a means of deciding the age of the deposits and their economic potential was the first time prehistory had ever been used for such a purpose.

The sand stones had fragments of charcoal on some surfaces but found no recognisable fossils.

The sediments of the past are many miles in collective thickness: yet the feeble silt of the rivers built them all from base to summit.

Geology is the science which investigates the successive changes that have taken place in the organic and inorganic kingdoms of nature; it enquires into the causes of these changes, and the influence which they have exerted in modifying the surface and external structure of our planet.

The Ozarks are old and worn mountains from the geological past.

Selenite occurs in abundance in well formed clear crystals of several inches in length.

The appearance of the bones of quadrupeds, especially those of complete bodies in the strata, tells us either that the layer itself which carries them was in earlier times dry land or that dry land was at least formed in the immediate area.

I used to dig around the sandbox and pull out pieces of coal and show them to my mother, and she used to say that's how I must have known I was going to be a geologist.

The lowest and most level land areas show us, especially when we dig there to very great depths, nothing but horizontal layers of material more or less varied, which almost all contain innumerable products of the sea.

Geologists have a saying - rocks remember.

The noble science of Geology loses glory from the extreme imperfection of the record. The crust of the earth with its embedded remains must not be looked at as a well-filled museum, but as a poor collection made at hazard and at rare intervals.

But the revolutions and changes which are responsible for the present state of the earth are not limited to the upsetting of the ancient strata and to the ebbing of the sea after the formations of new layers.

Bacteria mineralized the rocks; they deposited the iron. They made the geology we see.
