andesitic

The main composition of the volcano is andesitic and dacitic.

The initial activity was andesitic, but later became rhyolytic (12 Ma).

Also included are andesitic layers that can attain significant thicknesses in places.

The land is covered with the volcanic andesitic lava.

The average composition of the continental crust is andesitic.

A 500-m-wide crater caps the summit of the dominantly andesitic volcano.

There is a triple junction fault nearby and several andesitic volcanoes.

Activity continued for approximately 150,000 years in the form of quiet andesitic eruptions, as glaciation took place.

The andesitic volcano is topped with a lava dome.

As this process continues, the melt becomes more and more evolved eventually becoming andesitic.

The cone is largely andesitic, though basaltic and dacitic rocks are present.

It is composed of andesitic rather than basaltic lava.

The very lowest slopes of the fell again revert to andesitic lava flows.

It is considered to be the remnant of an extinct andesitic stratovolcano which formed between about 1.3 and 1.1 million years ago.

They had analysed the composition of the andesitic crust of Helliconia.

Taranaki is a perfectly formed andesitic strato-volcano, that last erupted in 1755.

Located in the centre east of the island, the canyon is a spectacular natural site, a wind funnel shaped from andesitic rock.

Yucamane is an andesitic stratovolcano group in southern Peru.

Lava flows from these volcanoes is basaltic and andesitic.

From about 900,000 years ago to the present, numerous andesitic volcanic centers in the area have come and disappeared through glacial erosion.

Little Barrier Island was formed by a relatively isolated andesitic volcano, active around 1 to 3 million years ago.

The most recent volcanic phase began about 4 mya, producing largely andesitic eruptions.

The lower flanks consist of mostly basaltic and some andesitic lavas.

Several largely andesitic volcanoes have erupted in Taranaki in the last two million years.

These andesitic igneous rocks were found only within the supposed impact feature as is shocked quartz.
