SUMMARY:Holme Park and Trowbarrow Quarries
DESCRIPTION:Leader: Carolina Goodship. Cumbria GeoConservation Group \nWe will be visiting two very different sites in and around the Arnside & Silverdale National Landscape to examine a variety of geological features in the Lower Carboniferous limestones\, including their lithology\, fossil record\, palaeokarst\, Quaternary karst features and structural geology. In the morning\, we will visit Holme Park Quarry. This is a working quarry operated by Holcim UK and our guide will be the quarry manager. The quarry extracts Lower Carboniferous Urswick Limestone which is crushed to produce a high-quality aggregate. The shallow dip of the limestone strata provides an  excellent opportunity to see the stratigraphic sequence of the Urswick limestone in its full unweathered technicolour glory. If have time\, we’ll include a short visit to see limestone pavement on an island in the middle of the quarry. The island is a nature reserve managed by the Cumbria Wildlife Trust. In the afternoon\, we will visit Trowbarrow\, near Silverdale. This disused quarry is a designated geological SSSI and \,local nature reserve\, managed by the Arnside & Silverdale National Landscape. In addition to its outstanding geology\, the quarry supports a rich and varied fauna and flora\, including several species of orchids. Trowbarrow is a key locality to study Urswick limestone geology and its ancient life. The site displays a wide variety of limestone types\, including evidence of emergence and outstanding examples of palaeokarst exposures. The limestone hosts a rich fossil community\, especially foraminifera (tiny single-celled organisms with shells). Macro fossils such as corals and brachiopods are also present\, along with excellent exposures of Thalassinoides trace fossils. Unlike the shallow dipping beds at Holme Park Quarry\, here the beds are oriented vertically – effects of the Variscan deformation known locally as the “Silverdale Disturbance.” \nContact the LGA secretary on lga.sec@btinternet.com for more information if you wish to attend.

SUMMARY:Flamborough: Sewerby – South Landing
DESCRIPTION:Leader: Richard Myerscough. FEAST \nChalk succession through the Upper Flamborough Formation with several regionally and nationally important biozones and marker horizons. Overlying are the glaciogenic and glaciofluvial Devensian and post Devensian tills\, sands\, and gravels. The interglacial Ipswichian Buried cliff cuts through the chalk sequence to form an internationally important feature. The Chalk is folded and faulted by the Flamborough Head Fault Zone with localised marbleisation and associated historical\, and vernacular associations. \nContact the LGA secretary on lga.sec@btinternet.com for more information if you wish to attend.

SUMMARY:The Upper Haslingden Flags\, Lee Quarry\, Bacup
DESCRIPTION:Leader: Dr Gareth Martin WYGT & LGA \nThe Upper Haslingden Flags (along with the Lower Haslingden Flags) are a unique sandstone unit in the Millstone Grit Group of the Carboniferous\, which was likely deposited in as a bird’s foot delta and is an expression of westerly source rocks into the Pennine Basin. Lee Quarry represents one of the best exposures of the Upper Haslingden Flags available and allows study of the rocks up close. The visit will focus on the rocks and their sedimentological features and the wider depositional environment when they were formed. \nContact the LGA secretary on lga.sec@btinternet.com for more information if you wish to attend.
