这份野外报告提供了地质信息的摘要，
复测了1：10000比例尺的图幅NY74NW和NE，以及NY75 SW、SE和NE。应当
参考已出版的地质标准图及野外地质资料
与这些地区相对应。
该地区包括阿尔斯顿地块的石炭纪沉积岩，阿尔斯顿地块是
英格兰北方石炭纪“块盆”构造。这些地层一般是平坦的
倾向平缓，但局部受到晚石炭世断层的干扰，其中许多断层
高度矿化的铅、锌、铁和钡矿石及伴生脉石矿物。
表层沉积物起源于晚德文斯冰期和随后的全新世
间歇性地覆盖基岩，厚度可达15米。
This field report provides a summary of geological information to accompany the recently
resurveyed 1:10 000-scale sheets NY74NW and NE, and NY75 SW, SE and NE. It should be
consulted in conjunction with the published geological standard maps and fieldslips
corresponding to these areas.
The area comprises Carboniferous sedimentary rocks of the Alston Block, a regional high of the
Carboniferous ‘block and basin’ structure of Northern England. These strata are generally flatlying
to gently dipping but are locally disturbed by late Carboniferous faults, many of which are
highly mineralised with ores of lead, zinc, iron and barium, and associated gangue minerals.
Superficial deposits originating for the late Devensian glaciation and subsequent Holocene
processes intermittently blanket the bedrock and can be up to 15 m thick.
