MISS  0GILV1E  ON  THE  WEN GEN  AND 
[Feb.  1893, 
(ii.)  The  Upper  Enneberg. 
Although  no  map  of  the  Abtey  portion  of  Enneberg  is  presented 
in  this  paper,  I  made  very  careful  observations  of  the  tectonic  rela¬ 
tions,  and  they  are  best  considered  in  conjunction  with  the  Prelongei 
district.  The  Wengen  and  St.  Cassian  strata  are  in  place  on  both 
sides  of  the  Enneberg  Talley ;  they  dip  on  the  Gardenazza  side 
westward,  and  on  the  Heiligkreuz  side  eastward.  The  succession 
in  the  northern  part  of  the  Gardenazza  massif  is  complete  from  the 
Tfengen  Beds  to  the  Dachstein  Dolomite ;  but  southward,  between 
Tarda  and  Colfuschg,  the  succession  is  broken  by  the  Groden  Pass 
faults,  and  the  Schlern  Dolomite  is  found  abutting  against  various 
horizons,  e.g.  at  Sass  Songe,  against  augite-porphyry  and  Wengen 
tuffs.  In  the  central  portion  of  the  massif  I urassic  and  Cretaceous 
strata  are  faulted  down,  the  relations  within  Gardenazza  showing 
a  general  similarity  to  those  in  the  large  4  Dachstein  ’  area  farther 
east. 
The  relations  of  the  strata  exposed  below  Heiligkreuz  Kofi  and 
La  Tarella  are  more  complicated. 
As  I  have  already  said,  in  describing  fig.  4  (pp.  25-27,  40),  the 
Baibl  Beds  appear  to  succeed  St.  Cassian  strata.  The  exposures  of 
acknowledged  Baibl  Beds  containing  Ostrcea  montis-caprilis,  Corbis 
Mellingi,  etc.,  lie  north  of  the  Heiligkreuz  Kirche.  They  strike 
N.  15°  W.,  dip  slightly  east,  and  are  succeeded  on  the  steep  slopes 
below  Kreuz  Kofi,  conformably  by  a  series  of  marls,  breccias,  beds  of 
dolomitic  limestone,  and  dolomite  interstratified  with  thinly-bedded 
dolomite-flags.  The  4  Heiligkreuz  Schichten’  behind  the  Kirche, 
which  contain  St.  Cassian  fossils,  strike  north-and-south,  and,  if 
followed  northward  along  their  strike,  would  continue  in  part 
directly  into  the  fossiliferous  Baibl  Beds,  while  above  them  are  strata 
belonging  to  a  higher  horizon  of  the  Baibl  Series  than  the  Ostrcea-. 
limestones.  A  slight  cross-fault  cuts,  therefore,  the  succession  of 
Baibl  Beds  just  north  of  the  Kirche  from  the  4  Heiligkreuz  strata.’ 
Going  southward,  the  Baibl  Beds,  now  with  a  different  strike 
(K.  15°  E.,  dip  45°  E.),  crop  out  all  along  the  road  and  strike 
against  different  horizons  of  the  same  system  of  St.  Cassian  strata 
as  that  to  which  the  exposures  at  the  Kirche  belong.  A  north-and- 
south  fault  is  thus  proved  between  the  Baibl  and  St.  Cassian 
Beds  here.  In  the  system  north  of  the  cross-fault,  owing  to  large 
slips  and  to  the  thick  surface-covering  of  fallen  blocks,  it  is  impos¬ 
sible  to  follow  this  north-and-south  fault,  but  better  evidence  of  its 
presence  is  found  farther  south.  Again,  on  the  Medis  Tvriese,  the 
whole  system  is  cut  by  a  cross-fault ;  and,  as  before,  the  St.  Cassian 
strata  are  faulted  up  on  the  southern  side. 
On  a  mountain  Alp,  above  the  woods  of  Peravuda,  there  are  steep 
exposures  of  the  grey  limestone-shales  (‘Heiligkreuz  Schichten’) 
and,  below  them,  St.  Cassian  limestones  full  of  fossils  ( Halobia 
Richthofeni ,  Mytilus  Munsteri ,  corals,  etc.).  Still  farther  south  a 
ridge  may  be  seen  running  out  towards  Bu.  I  did  not  myself 
examine  it,  but  Dr.  Bothpletz  has  kindly  communicated  to  me
