Llangynog. The relationship,. if ttny, of the known
mineralisation 1 ’ ’ tti the ‘Bougue3. ‘anomzilies remains
obscure. More detailed gr&ity *surveys ‘of specific
Bouguer anomaly features, such as’ those near Craig-y-
Glyn [SJ 10 301 and the low northwest of Ll&ngynog [SJ

relationships to nearby mineralisation. * 1
