The genesis of the deposit has previously been argued to be of hydrothermal-vein type or of skarn-hydrothermal type.In this study, we report the results of Rb-Sr isotopic dating based on sphalerites from the main orebody of the Hongdonggou Pb-Zn polymetallic ore deposit, which yield an isochron age of 135.7 ± 3.2 Ma, constraining the timing of mineralization as early Cretaceous.Combining the results from this study with those from previous work, we propose that the Hongdonggou Pb-Zn polymetallic ore deposit is a hydrothermal-vein deposit associated with the early Cretaceous tectonothermal event, and the mineralization is controlled by NW- and near EW-trending faults in the Luanchuan Mo-W-Pb-Zn-Ag polymetallic ore concentration belt.The most widely known form of radiometric dating is carbon-14 dating.Ken Ham is often quoted as rejecting historical science by rhetorically asking “Were you there?” In other words, we cannot know historical processes because we did not observe them.Fossils can't form in the igneous rock that usually does contain the isotopes.
Without the starting time it is Actually, knowing the starting time is still not enough.
Poor Ken , he has a thing about “billions of years” and resorts to porkies to reject them.
This is a good summary of why his recent porkies are pure Ham. utm_source=feedburner&utm_medium=email&utm_campaign=Feed: Science And Religion AView From An Evolutionary Creationist (Science and Religion: A View from an Evolutionary Creationist) I don’t know why he does it Answers in Genesis now has a “Check this Out” feature where they tackle a scientific claim which argues for an old earth and try to debunk it.
Consequently, when the narrator of this video says “we don’t” in answer to how we can know how some of our assumptions about radiometric dating are correct, it is this philosophical bent in action.
Such a perspective is facile, as it completely disregards the fact that we reconstruct past events every day at all levels, from the simple act of encountering a broken glass on the floor with ice and water beside it (someone dropped a glass of water) to complex murder investigations in which no one but the murderer was present.
