This book is dedicated to the memory of
Maria Adela Montalvo, my wife. She was a
key technical assistant for several works done
by the geological group from the Department
of Geology-La Plata Museum and National
Research Council, on the San Rafael Block
and other argentine regions for more than 40
years. She crossed successfully technical
secretary ‘paradigms’: the old and the
electric typewriter and finally the computer
systems, always with enthusiastic expertise.

Preface
The aim of the book is to offer all available information, largely presented at
scientific conferences and meetings about the pre-Carboniferous units of the San
RafaelBlock,compiledafterover15yearsofresearchintheareacarriedoutbythe
working group. The opportunityto presentdata in theSpringerPublishing enables
greater visibility of all data available to an international audience. A first proposal
was made in 2013, with the support and enthusiasm of Dr. Jorge Rabassa as
regional editor, for the series of Springer Briefs, but we soon realized that this
wouldnotbeenoughinordertopublishthefulldataset.Itwasthereforerequested
to Springer to change to Earth Sciences Series of Books and the deadline was
extendeduntil2016 that finally constitutes theworkpresentedheretobe available
to the geological community. We hope that this book to be a review of the state
oftheartinthefieldthatstimulatesmorediscussionsabouttheSanRafaelBlock’s
geological evolution, in the context of the proto-Andean Gondwana margin.

assistance. A special recognition is for Norberto Uriz (University of La Plata), for
his tireless collaboration to improve and even to ‘create’ the illustrations that are
presented thorough the book. Thanks to Paulina Abre for helping us in language
correctionof theearly draft chapters. The actual working group of theDepartment
of Geology at La Plata Museum: Andrea Bidone, Mario Campaña, Arón Siccardi,
Miguel Cricenti is deeply acknowledged. A remembrance to Humberto Lagiglia,
sinceduringhisdaysasdirectoroftheMuseoMunicipaldeHistoriaNaturalofSan
Rafael, illustrated us with his knowledge of archeology of the area and kindly
offered logistic support during several fieldworks carried out by the working
research group. I also deeply thank Sofía de Occhipinti and her family from Villa
25 de Mayo for their loving hospitality. A profound remembrance is to the late
ProfessorsattheUniversityofLaPlataAlfredoJ.Cuerda,OsvaldoC.Schauerand
Luis Dalla Salda, who had participated in these investigations. I have received
importantlaboratorysupportfromtheCIG-GeologicalResearchCentresincemany
