Bleach zone

English to Spanish Tech/Engineering Mining & Minerals / Gems

Hola a todos, el fragmento en el que aparece el término dice lo siguiente:

• Bleach zone – due to the oxidation of pyrite there are areas where RQD is low and oxide material similar to topsoil are present. These areas can be identified when drilling penetration rate is high then normal and also these data can be identified through the modelling of diamond drill holes.

¡Muchas gracias por su ayuda!
