Youngest Moon rocks

According to Official Guinness Records,

The youngest Moon rocks date back some 3.2 billion years. They are a type of volcanic basalt, originating from the dark lunar maria (seas). They are not dissimilar to the age of the oldest dateable rocks on Earth. Lunar samples measuring 382 kg (842 lb) from Apollo missions have been returned to Earth. Less than 1 kg has been returned from the Soviet Luna missions.
