Granite batholith radiometric dating
Field and textural data have established that these granite phases were sequentially intruded while still hot. Radiohalos in granites: Evidence for accelerated nuclear decay. That these granitic phases were intruded as hot magma is also confirmed by analytical and experimental data. In Radioisotopes and the age of the earth: Results of a young-earth creationist research initiative, ed. He argued that because the polonium (Po) radiohalos within biotite grains in granites appeared to be “orphaned” (there apparently being no precursor or parent atoms in situ), and they thus had to form extremely rapidly (due to the fleeting existence of two of the polonium isotopes), the Po radiohalos and the granites hosting them had to have been created in a fiat manner by God. He concluded the granites are primordial rocks and termed the Po radiohalos as God’s “fingerprints of creation.” The observation that many granite bodies intrude fossil-bearing sedimentary rocks which were deposited during the Flood is not considered an obstacle to this proposal for the instantaneous origin of granites.
Sills are parallel to beds of surrounding rock, usually horizontal in nature.
Only one of these studies included an investigation of the contact zone around a granite body.
Also, no previous studies examined discrete, separate granite bodies that had intruded into one another sequentially.
Sedimentary rocks in the contact zone were metamorphosed by the hot magma. In Radioisotopes and the age of the earth: Results of a young-earth creationist research initiative, ed.
