he became known as the “father of english stratigraphy” because he gave geology a descriptive methodology for assigning relative ages to the various formations. after many years of field observations, he published three works from 1815 to 1817, which contained the first geological map of england and wales and an explanation of the order and relative chronology of the stratigraphic formations as defined by certain characteristic (or index) fossils rather than the mineralogical character of the rocks. on the continent johann lehmann (1719-1767), a mining and mineralogy professor in berlin, carefully studied german mountain strata and recognized three classes of rocks: the non-fossil-bearing and greatly inclined rocks in the high mountains (formed during creation week), fossiliferous rocks resting roughly horizontally on the flanks of the mountains (attributed to the flood) and loosely consolidated rocks on top of these (produced after the flood by accidents of nature from time to time). geologists concluded that the earth was tens of thousands, if not millions, of years old and the relatively recent noachian flood affected only the rounded valleys and hills carved into consolidated strata and deposited only the superficial gravels and boulders (c.

those principles laid the foundation for modern geology and are still taught and used by geologists today, although most of them probably have no idea that steno was a bible-believing young-earth creationist. this type of "relative dating" to work it must be known. in 1863 the great english physicist lord kelvin (1824-1907) used thermodynamics related to the internal heat of the earth to argue for a “young” age of the earth of only about 98 million years, much too short for darwin’s theory (which he rejected). erroneous thinking was especially applied to the antiquity of man relative to the earth.

although playfair made no attempt to harmonize hutton’s theory with scripture, he did defend hutton’s notion of the earth’s great antiquity by asserting that the bible only addresses the time-scale of human history, which hutton did not deny was relatively short, as the biblical chronology indicates..Several scriptural geologists raised objections to this use of fossil shells in dating the strata, referring both to uncertainties in taxonomic classification of shells and to ambiguities about their geological distribution. massive blow to catastrophism came between 1830 and 1833, when charles lyell (1797-1875), a lawyer by training as well as a former student of buckland, published his masterful three-volume work, principles of geology. that volume illustrates and describes hundreds of ammonite species in minute detail.

") while the "official" principles pertain to layers of rock and their shapes and orientations, steno's own principles were strictly about "solids within solids. of earth history according to the three views of the early 19th century. 1828 lyell worked out his interpretation of the tertiary (on which the first and later editions of his principles of geology depended) solely on the basis of shells (lyell, 1863) even though he did not start studying “conchology” until 1830 (lyell, 1881). between 1903 and 1906, the famous new zealand physicist ernest rutherford (1871-1937) determined that isotopes could be used to date rocks.
