Woodmorappe Can't Read Rb-Sr Diagrams

The following material may be freely copied and distributed as long as the author is properly acknowledged and the material is not altered, edited or sold. Woodmorappe (1979, p. 122) attacks the validity of Rb-Sr isochron dating by claiming that the Pahrump Group 'Diabase ' in California has been dated at 'no less than 34 billion years', which is approximately twice the age of the Big Bang and more than 7 times the age of the Earth!! Of course, both geologists and YECs agree that a 'date ' of 34 billion years for this rock is completely ridiculous. Geochronologist Dalrymple (1984, p. 77-79) discusses the origin of this 'date ' and denounces Woodmorappe (1979, p. 122) for misreading a 87Sr/86Sr vs. 87Rb/86Sr plot for the Pahrump Group 'Diabase'. The original sources of the Pahrump Group 'Diabase ' Rb-Sr diagram are Wasserburg et al. (1964, p. 4397) and Faure and Powell (1972, p. 101-102). The diagram of the 'diabase ' shows a terrible scatter and does NOT provide an isochron and an associated Rb-Sr date. Radiometric dating on related rocks, however, suggest
