The type of plate boundary referred here is defined as an ocean-Continent Convergent Plate Boundary.
<h3>What is an ocean-continent convergent plate boundary?</h3>
An ocean-continent convergent boundary is a limit in which the oceanic plate is forced underneath the continental plate.
This type of boundary occurs when an oceanic lithospheric plate crashes against to a continental plate.
In conclusion, the type of plate boundary here is defined as an ocean-Continent Convergent Plate Boundary.

Answer:
potassium-argon dating
Explanation:
Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash. It is most applicable for dating minerals and rocks more than 100,000 years old. It is based on measuring the product of the radioactive decay of an isotope of potassium (k) into argon (Ar). Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.
