Tree bark sampling is a geochemical exploration technique to find minerals in tree bark, used in cold areas where standard soil sampling isn't possible.

Tree Bark Sampling

In rare cases where conditions on the ground discourage other types of geochemical surveying it may be necessary to sample tree bark. Tree bark in appropriate zones is harvested and tested for mineralization much like soil samples. Due to the biological nature of the samples, careful interpretation is required and only certain elements can be accurately analysed.
