Where metamorphic petrology is of obvious help is in the area of decarbonation reactions. Although fluid pressures are higher, there are well known reaction sequences. In particular the reaction ... 

Twenty or thirty years ago arguments indicating that the rocks being studied have approached chemical equilibrium were an important part of all metamorphic petrology... 

In the 1980s, reviews and textbooks by Kisch (1983) and Frey (1987) summarized the illite crystallinity concept mostly from a petrogenetic point of view. Subsequently, the illite crystallinity method has been incr easingly and extensively applied all over the world as an empirical metamorphic petrological tool (for outstanding examples, see Merriman and Frey 1999). Simultaneously, studies to understand the mineral structural,... 

The rare earth elements (REE) are the most useful of all trace elements and REE studies have important applications in igneous, sedimentary and metamorphic petrology. The REE comprise the series of metals with atomic numbers 57 to 71 — La to Lu (Table 4.4). In addition, the element Y with an ionic radius similar to that of the REE Ho is sometimes included. Typically the low-atomic-number members of the series are termed the light rare earths (LREE), those with the higher atomic... 

The reader will detect a number of biases in this book which are an inevitable consequence of the author s geological interests. The first bias is towards examples chosen from the Archaean, which is the principal area of geology iii which I have worked and which is evident also from the place of writing. The second bias is towards igneous and metamorphic petrology, which again are my fields of interest, but also the area in which many of the methods described were first applied. 

How do you do this And why would it be useful A complete answer would take a whole book, and is more appropriate to a course in metamorphic petrology, but we can fairly easily see how thermodynamics is applied in such cases. Newton and Haselton (1981) give a summary of the thermodynamics of this reaction, as well as its use as a geobarometer, that is, a mineral assemblage that, when analyzed thermodynamically, will give an estimate of the pressure at the time the minerals equilibrated.

The fact that most metamorphic inclusions are secondary has led to the diffuse opinion that they are useless. Notwithstanding the evidence that they are an intrinsic part of the rock and have consequently to be studied, I see the problem in an entirely different way primary and secondary inclusions are exactly alike neither is "a priori" secure as any is liable to have suffered one of the many processes which may alter the representativity of the enclosed fluid, such as selective trapping, leakage, necking down or reaction with the host mineral. Therefore any fluid inclusion data must be compared with results derived independently by other methods. This is the point at which we are now, as many of these data became available in metamorphic petrology from experimentation or theoretical models. Only when some limiting conditions have been fulfilled may additional data be obtained and it comes then...
