Abstract - Summary 
(short description):
The restitic Hf-zircon and U-thorite of early Precambrian age prevail among accessory zircons and thorites of quartz gabbro-norite-dolerites in the intrusive Ayu-Dag of the middle Jurassic age. This demonstrates the existence of fragments of ancient continental crust with highly radioactive granite bodies within the mezozoids of the basement in Highland Crimea.
Key words: restitic zircon and thorite; basement of Highland Crimea.
