Eskdalemuir Observatory Monthly Magnetic Bulletin: November 2013

[摘要] This report describes interpretations of Chalk macrofossils for 49 localities in the Henley-on- Thames district (Sheet 254). The lithostratigraphical units identified comprise: Holywell Nodular Chalk, New Pit Chalk, Lewes Nodular Chalk and Seaford Chalk Formation, spanning the Turonian and Coniacian stages and Mytiloides spp., Terebratulina lata, Plesiocorys (Sternotaxis) plana, Micraster cortestudinarium and lower Micraster coranguinum biozones. This work is in connection with a strategic survey of Chalk Group lithostratigraphy on the northern flank of the Thames Basin, to permit high-resolution facies modelling of the Chalk of southern England.
