This will be your introduction day to Shetland geology and landscapes. We will study part of the largest rock group in Shetland that belongs to the Dalradian Supergroup of Scotland. We examine upper Dalradian phyllites, intrusive and extrusive volcanics, a serpentinised komatiite lava (the birthplace of Iapetus Ocean?), Viking steatite (soapstone, talc) workings and a massive sulphite deposit.

Day 2. Unst.

A scenic drive to the island of Unst crossing the island of Yell. This is a unique chance to see the most complete section through ancient ocean crust in the British Isles; the Shetland Ophiolite. In doing so we visit a talc quarry, a serpentinite pebble beach, a horse mill and abandoned chromite workings.

Day 3. West to East Traverse.
Boudins - Burn of Kirkhouse

A traverse from West to East across Mainland to study rocks that lie east of the Walls Boundary Fault. We visit fine exposures of Moine and lower Dalradian metamorphic sequences repeated by the Nesting Fault (a splay of the WBF) and study their relationships. We will study the enigmatic Valayre Gneiss, a microcline-megacryst porphyroblast gneiss) one of Britain's most spectacular rocks.

Day 4. Northmaven.
Back Sand - Ollaberry

We travel north to scenic Mavis Grind where the Atlantic is just a stones throw from the North Sea to visit the Northmaven Plutonic Complex of north Mainland. This is a post tectonic plutonic intrusion and we will see ring dyke rocks, diorite and gabbro, granite and granophyre. We will also follow the Walls Boundary Fault, the manifestation of the Great Glen Fault in Shetland and visit its best ('hands on') exposure in Scotland. We will also get a view of Sullom Voe Oil Terminal as we stop to examine some Storegga Slide Tsunami deposits.

Day 5. Eshaness.

Most of the day will be spent on the spectacular volcanic rocks of the Eshaness peninsula. The rocks here formed by volcanism in a late Devonian sedimentary basin. We will study the finest section through the side of a volcano in the British Isles in the dramatic cliffs showing agglomerate, lava flows and ignimbrite. We will examine a most amazing storm 'beach' that is being formed by our winter storm waves. Our return journey will allow us to see how ice carved Shetland's deepest fjord and sculpted its highest hill.

Day 6. South Mainland.
Lake sediments, Exnaboe

Today we examine exposures of the South-east Shetland Devonian intermontane sedimentary basin in south Mainland. We will see superb dune, river and lake sediments including fish beds. We shall also make a detour to visit Shetland's rarest glacial erratic.

Day 7 (half day).
Quarff River Valley

Quarff and Lerwick. Excellent exposures of the more proximal part of the South-east Shetland sedimentary basin visiting basal breccia, braided river and alluvial fan deposits.

(This itinerary assumes Lerwick as its daily point of departure).
