Group of volcanic rock formations in northwestern England

Eycott Volcanic Group Stratigraphic range: Ordovician (Llandeilo to Caradoc epochs) Type Group Sub-units Potts Ghyll Formation, Overwater Formation Underlies unconformity Overlies Skiddaw Group Thickness to 3200m Lithology Primary andesitic lavas and sills Other volcanic breccias, tuffs, sandstone Location Region Cumbria Country England Extent northern Lake District & Melmerby Fell inlier Type section Named for Eycott Hill

The **Eycott Volcanic Group** is a [group](/source/Group_(stratigraphy)) of [volcanic](/source/Volcanic) rock formations of [Ordovician](/source/Ordovician) age ([Llandeilo](/source/Ordovician#Subdivisions) to [Caradoc](/source/Ordovician#Subdivisions) [epochs](/source/Epoch_(geology))) named after the locality of Eycott Hill in the English [Lake District](/source/Lake_District).[1] The group overlies the [Skiddaw Group](/source/Lake_District#Northern_Fells) and is [unconformably](/source/Unconformity) overlain by a variety of different [Devonian](/source/Devonian) and [Carboniferous](/source/Carboniferous) age rocks.

This rock sequence has previously been known as the **Eycott Group**.[2] It consists largely of [andesitic](/source/Andesite) [lavas](/source/Lava) and [sills](/source/Sill_(geology)) with [tuffs](/source/Tuff), [breccias](/source/Breccia) and volcaniclastic [sandstones](/source/Sandstone). Its main outcrop is in an east-west oriented band of country in the northern part of the Skiddaw range in the northern Lake District stretching from the village of [Bothel](/source/Bothel%2C_Cumbria) east to form the hill of [Binsey](/source/Binsey%2C_Cumbria) and further east, the more extensive [Caldbeck Fells](/source/Caldbeck). A smaller outcrop underlies [Greystoke Park](/source/Greystoke_Castle) just to the east of this area and forms Eycott Hill east of [Mungrisdale](/source/Mungrisdale). There is a further [inlier](/source/Inliers_and_outliers_(geology)) at [Melmerby Fell](/source/Melmerby%2C_Cumbria) in the [North Pennines](/source/North_Pennines). The outcrops are intensely faulted and in the Caldbeck area are crossed by numerous [mineral veins](/source/Vein_(geology)) yielding [arsenic](/source/Arsenic), [barium](/source/Barium), [copper](/source/Copper) and [lead](/source/Lead) which have been worked in the past.
