The Antiquity of Man The highly fossiliferous limestones of the Trenton tell of clear water and abundant life. The Elements of Geology Hence it will follow that great violations of continuity in the chronological series of fossiliferous rocks will always exist, and the imperfection of the record, though lessened, will never be removed by future discoveries.

A History of Science — Volume 3 The general adoption by geologists of the term stratified, as applied to these rocks, sufficiently attests their division into beds very analogous, at least in form, to ordinary fossiliferous strata. The Student's Elements of Geology On their sudden appearance in the lowest known fossiliferous strata. On the Origin of Species By Means of Natural Selection, or, the Preservation of Favoured Races in the Struggle for Life On the western side of the Fiord of Christiania, in Norway, there is a large district of trap, chiefly greenstone- porphyry and syenitic-greenstone, resting on fossiliferous strata. The Student's Elements of Geology The accumulation of each great fossiliferous formation will be recognised as having depended on an unusual occurrence of favourable circumstances, and the blank intervals between the successive stages as having been of vast duration. The Origin of Species by means of Natural Selection, 6th Edition The aqueous or fossiliferous rocks having now been described, we have next to examine those which may be called volcanic, in the most extended sense of that term. The Student's Elements of Geology Thus, for example, we behold alike in the crystalline and fossiliferous formations an alternation of beds varying greatly in composition, colour, and thickness. The Student's Elements of Geology We meet occasionally with extremely compact beds of volcanic materials, interstratified with fossiliferous rocks. The Student's Elements of Geology Diagram of fossiliferous rocks. — of plutonic and sedimentary formations. The Student's Elements of Geology Until recently these were regarded as the oldest fossiliferous rocks. The Origin of Species by means of Natural Selection, 6th Edition Superposition, therefore, is not of the same value as a test of age in the unstratified volcanic rocks as in fossiliferous formations. The Student's Elements of Geology A Plutonic rock, therefore, must, in general, be of considerable antiquity relatively to the fossiliferous and volcanic formations, before it becomes extensively visible. The Student's Elements of Geology By evidence of this kind we can establish a coincidence in age between volcanic rocks and the different primary, secondary, and tertiary fossiliferous strata. The Student's Elements of Geology It is also not uncommon to find a conglomerate almost exclusively composed of rolled pebbles of trap, associated with some fossiliferous stratified formation in the neighbourhood of massive trap. The Student's Elements of Geology To the question why we do not find rich fossiliferous deposits belonging to these assumed earliest periods prior to the Cambrian system, I can give no satisfactory answer. The Origin of Species by means of Natural Selection, 6th Edition If the pebbles agree generally in mineral character with the latter, we are then enabled to determine its relative age by knowing that of the fossiliferous strata associated with the conglomerate. The Student's Elements of Geology They traverse all kinds of rocks, both hypogene and fossiliferous, and extend downward to indefinite or unknown depths. The Student's Elements of Geology Part of the primary fossiliferous strata, No. I, have also been raised to the surface by the same gradual process. The Student's Elements of Geology Such clay-slates, in fact, are variable in composition, and sometimes alternate with fossiliferous strata, so that they may be said to belong almost equally to the sedimentary and metamorphic order of rocks. The Student's Elements of Geology That region had already acquired in some degree its present configuration before any volcanoes were in activity, and before any igneous matter was superimposed upon the granitic and fossiliferous formations. The Student's Elements of Geology It may perhaps be suggested that some metamorphic strata, and some granites, may be anterior in date to the oldest of the primary fossiliferous rocks. The Student's Elements of Geology But so greatly are our views now changed, that we find it no easy task to point out a single mass of granite demonstrably more ancient than known fossiliferous deposits. The Student's Elements of Geology In order, therefore, to establish a chronological succession of fossiliferous groups, a geologist must begin with a single section in which several sets of strata lie one upon the other. The Student's Elements of Geology For reasons already stated, I proceed first to treat of the aqueous or fossiliferous formations considered in chronological order or in relation to the different periods at which they have been deposited. The Student's Elements of Geology The aqueous rocks, sometimes called the sedimentary, or fossiliferous, cover a larger part of the earth's surface than any others. The Student's Elements of Geology The beds sometimes consist of an alternation of substances varying in colour, composition, and thickness, precisely as we see in stratified fossiliferous deposits. The Student's Elements of Geology Norway, Cambrian of. —, foliation of crystalline schists in. —, granite veins in gneiss of. —, granite altering fossiliferous strata in. The Student's Elements of Geology In other words, the destroying and renovating processes have given birth to new rocks below, while those above, whether crystalline or fossiliferous, have remained in their ancient condition.
