The SHRIMP (Sensitive High Resolution Ion Microprobe) enables the accurate determination of the uranium-lead age of the mineral zircon, and this has revolutionized the understanding of the isotopic age of formation of zircon-bearing igneous granitic rocks.Another technological development is the ICP-MS (Inductively Coupled Plasma Mass Spectrometer), which is able to provide the isotopic age of the minerals zircon, titanite, rutile, and monazite.Don't miss any communication—with your permission, we will send you push notifications to let you know of new messages in your inbox!

It doesn’t matter if you’re a new pup just dipping your toe in the water or a vet with your own fursuit, we hope you’ll find you belong here. You can customize your Global and Local Newsfeeds by setting your site-wide filter with basic criteria—from physical attributes like height, weight and body type to personal info like type of fursona and relationship status.
The filter can be easily turned on and off, allowing you to seamlessly switch between a global and customized site experience. Just install our i OS or Android app that you will find in the Apple App Store or Google Play Store.
Take a moment to play with the criteria in order to get it right—try narrowing and broadening it until you find the right balance. The mobile apps have been designed to deliver an experience tailored for smaller screens, and uses the device native APIs.
These minerals are common to many igneous and metamorphic rocks.
Such techniques have had an enormous impact on scientific knowledge of Earth history because precise dates can now be obtained on rocks in all orogenic (mountain) belts ranging in age from the early Archean (about 4 billion years old) to the early Neogene (roughly 20 million years old).
