“…This normal succession compares well (apart from F. cf. exilis bcs) with the sequential relationship obtained by Smith (1957) of Lycospore to Transition to Densospore phases, and is similar to those observed by Corsin et al (1967) in Westphalian C coals and Habib (1966) in Westphalian D age coals. Smith (1962) recognized a fourth phase, termed Incursion, which was characterized by the association of Crassispora kosankei (Potonie & Kremp) Smith &Butterworth 1967 andPunctatosporites minutus I brahim 1933.…”

“…He concluded that three phases could be recognized corresponding to high numbers of two species of the genus Lyeospora, and one species from each of the genera Laevigatosporites and Densosporites, and that these phases occurred sequentially. Other authors have carried out similar analyses in France (Corsin et al 1967), Canada (Hacquebard & Donaldson 1969) and Russia (Koval'chuk & Uziyuk 1973) but only recorded miospore genera. Use of miospore genera is likely to make the palaeoecological interpretation more difficult and it increases the possibility of grouping miospore species whose parent plants may have existed in different habitats.…”

“…However, Paget (1936Paget ( , 1937, Butterworth (1956) and Smith & Butterworth (1967) used miospores for correlation of the seams comprising the Warwickshire Thick Coal. Detailed information on the vertical distribution of miospores within individual seams was published by Smith (1957Smith ( , 1962Smith ( , 1964 who worked on coal seams in the Yorkshire Coalfield, and by Corsin et al (1967) in France and Habib (1966) in America. Recently much research has been carried out into the sedimentary environments in which modern peat, a histosol, has developed both in the USA, e.g.…”

The Warwickshire Thick Coal is of Westphalian B age, and it developed at the southern margin of the Pennine Basin in central England. It usually consists of three to five leaves of coal which can total up to 8.5 m in thickness. Palynological analysis of the leaves has revealed the presence of four miospore types which occur in similar successions in each leaf. These coals are interpreted as long-residence histosols. Comparable successions have been recognized by other authors and a variety of mechanisms advanced for their formation. The model proposed to account for their origin is change in vegetation due to variations in water table (hydroseral growth), which occur during the development of ombrotrophic bogs similar to those found in the Far East. Many inter-related factors are believed to affect water table variation including climate, topography and raising of the bog surface (the latter controlled by both differential rate of subsidence and accumulation of plant debris). It is probable that the model proposed may be applicable to other coal seams, and this has implications for coal exploration. Estimation of regional rates of subsidence may help in the location of thick long-residence histosols, and examination of miospore cycles within leaves of coal may be useful in predicting the proximity of seam splits.

“…There are other densospore producers, such as Porostrobus (Chaloner, 1962;Leary and Mickle, 1989). However, the consistent co-occurrences of megaspores, such as Zonalesporites from Sporangiostrobus, have aided significantly in separating the taxonomic source of densospores in coals and shales (Grebe, 1966;Corsin et al, 1967;Pierart, 1968;Scott and King, 1981;Bartram, 1987;Wagner, 1989). Given the environmental significance attributed to densospore producers, a major study is needed in which megaspores are considered, and consequent finer taxonomic resolution used in making environmental inferences.…”

“…Few environmental clues exist regarding densospore producers, and those that do are largely anecdotal, not welded into a complete picture. Densosporites (or Sporangiostrobus) has been found in shaley coals and in outright clastic deposits by several authors (e.g., Urban, 1962;Corsin et al, 1967;Ravn, 1979;Wagner, 1989) and Smith (1962) notes the high incidence of Incursions (with associated elastics) following Densospore phases. It has been suggested by Wagner (1989) that Sporangiostrobus occurs in coal balls but has been consistently overlooked, with exceptions (Leisman, 1970).…”
