A panegyric (US: / ˌ p æ n ɪ ˈ dʒ ɪ r ɪ k / or UK: / ˌ p æ n ɪ ˈ dʒ aɪ r ɪ k /) is a formal public speech or written verse, delivered in high praise of a person or thing. [1] The original panegyrics were speeches delivered at public events in ancient Athens.
Pliny's panegyric was set at the beginning of the collection as classical model of the genre. [1] Sometimes the author of the last speech, Pacatus, is credited as the editor of the final corpus . [ 39 ] [ 40 ] This belief is founded on the position of Pacatus' speech in the corpus —second after Pliny's—and because of the heavy debt Pacatus ...

The panegyreis were festivals in which prayers were made, sacrifices offered, and also processions. [4]

Igneous rocks include volcanic and plutonic rocks. [4] Sedimentary petrology focuses on the composition and texture of sedimentary rocks (rocks such as sandstone, shale, or limestone which consist of pieces or particles derived from other rocks or biological or chemical deposits, and are usually bound together in a matrix of finer material).
Evidence for pressure solution has been described from sedimentary rocks that have only been affected by compaction. The most common example of this is bedding plane parallel stylolites developed in carbonates. In a tectonic manner, deformed rocks also show evidence of pressure solution including stylolites at a high angle to bedding. [4]
[1] [2] Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, [3] and rock gypsum, an aggregate of crystals of the mineral gypsum. [4] Lapis lazuli is a type of rock composed of an aggregate of crystals of many minerals including lazurite , pyrite , phlogopite , calcite , potassium feldspar , wollastonite and some ...
The aim of sedimentology, studying sediments, is to derive information on the depositional conditions which acted to deposit the rock unit, and the relation of the individual rock units in a basin into a coherent understanding of the evolution of the sedimentary sequences and basins, and thus, the Earth's geological history as a whole.
