Paleomagnetism Research suggests great pyramid stones are cast.

A study indicates that the great pyramids stones where cast based on paleomagnetism research:

From the reviews:”This new encyclopedia focuses mainly on the magnetic field of internal origin; however, some related articles on external sources are included. The editor’s goal is to cover the subject in fine detail at a level understandable to anyone with a general scientific education. The work includes 318 alphabetically arranged entries written by 226 specialists in the field. Each entry has a short bibliography and cross-references. 
 Summing Up: Recommended. Upper-level undergraduates through professionals/practitioners.” (L. Joseph, CHOICE, Vol. 45 (6), 2008)”This new Encyclopedia 
 present universal knowledge in the fields of Geomagnetism and Paleomagnetism in the broadest sense and in a single volume. 
 Written at a level accessible to anyone with a scientific education, this authoritative and speedy reference is 
 to all whose activities or studies are concerned with both fields. It is therefore a valuable working tool not only for geophysicists and geophysics students but also for physicists, geologists, geographers, atmospheric and environmental scientists and engineers.” (Jozef Hus and Jean-Claude Jodogne, Physicalia Magazine, Vol. 30 (1), 2008)”The Encyclopedia of Geomagnetism and Paleomagnetism is part of the Encyclopedia of Earth Sciences Series. 
 Numerous diagrams, pictures, tables, formulas, and mathematical equations provide clarity to the discussions. A detailed 44-page subject index and a series of color plates, mostly magnetic field maps, appear at the end of the volume. 
 this encyclopedia will be of particular interest to students and professionals in the earth sciences. This work is recommended for college, university, and larger public libraries.” (Ignacio J. Ferrer-Vinent, ARBAonline, Vol. 39, 2008)”This is major work whose aim is to provide a comprehensive review of all aspects of geomagnetism and palaeomagnetism as the subjects are currently understood. 
 the articles are well illustrated, well written and comprehensible to the reader. 
 I do believe that it is an indispensible library tool for graduates, academics and professionals alike involved in the application or study of geomagnetism and palaeomagnetism. For those already involved in a particular aspect of this broad discipline it provides a useful pathway to allied subjects.” (Graeme Taylor, Geological Magazine, Vol. 145 (3), 2008)”This volume claims to be the first single encyclopaedia to cover the combined fields of geomagnetism and paleomagnetism. 
 aims to provide a comprehensive and authoritative coverage of these complex and ever expanding subjects. 
 A very useful list of cross-references is provided at the end of each article, which makes it much easier to link together areas that are less familiar. 
 In the main this book is for those specialising in geophysics 
 . vital for academic libraries with geology and geophysics departments.” (Helen Ashton, Reference Reviews, Vol. 22 (3), 2008)
