How old is a rock if the mineral biotite from the rock has 85,000 40K atoms and 15.000 40Ar atoms? Note: 40K decays to 40Ar with half-life = 1.3 billion years. 2. Isotopic analysis of a granitic intrusion indicates that 6.25 % of the original 40K is present. Analysis of a nearby basaltic intrusion indicates that 25 % of the original amount of 40K is present. What is the absolute age of both the granitic intrusion and the dike? What is the relationship between them? I. 3. Pebbles of an igneous rock are incorporated within a conglomerate.

Group of answer choices Scientists originally believed that the Chicxulub crater was caused by a nuclear blast since the impact residue (e.g., melted bedrock, tektites, shocked quartz, etc.) discovered there was very similar to that found around nuclear test sites. According to a well-established hypothesis, a meteor the size of a mountain slammed into Earth about 65 million years ago, filling the atmosphere with gas, dust, and debris that drastically altered the climate. One key piece of evidence is a very high level of iridium in a layer of Earth, with lots of dinosaur fossils below but none above. A huge impact crater linked to the impact event was found around coast of Mexico’s Yucatán Peninsula. Although the impact occurred in the Gulf of Mexico, meteorite debris from the 'dinosaur rock' was discovered all over the world.arrow_forward
